The goal of the RCSOC is to improve the diversity in Open Source development. It allows groups of 2 women students to work full-time on a FOSS project (such as API Platform) during the summer. Students are paid and mentored.
Rails Girls Summer of Code is a global fellowship program for women and non-binary coders. Students receive a three-month scholarship to work on existing Open Source projects and expand their skill set.
Our worker cooperative, Les-Tilleuls.coop, will also support the program by providing money, coaches (including me) and desktops (in Lille, France):
In our company, we attempt as much as possible to support associations engaged in the fight against social inequalities, or involved in a better access to culture and respect of the environment. Since our foundation in 2011, we have always upheld diversity in Open Source. Thus, it’s no surprise that we support Rails Girls’s Summer of Code program.
If you’re interested in working 3 months with us to improve cutting-edge Open Source projects, don’t by shy, apply!
Ce programme vise à favoriser la diversité dans le mode du logiciel libre. Il permet à des groupes de 2 étudiantes d’être payées durant l’été pour travailler (en binôme) sur des projets Open Source.
Notre SCOPLes-Tilleuls.coop participe également au programme en tant que sponsor, et va fournir des bureaux (à Euratechnologies, Lille) et des “coachs” afin d’accompagner les participantes :
Chez Les-Tilleuls.coop, nous tentons autant que possible d’accompagner des associations ou des entités engagées dans la lutte contre les inégalités sociales, l’accès à la culture, la formation, ou encore le respect de l’environnement. Notre coopérative s’implique aussi dans une meilleure diversité dans le numérique et c’est donc avec une certaine évidence que nous apportons notre soutien au programme “Summer of Code 2018” organisé par l’association Rails Girls (RGSoC).
Si vous êtes intéressées pour travailler 3 mois sur des projets Open Source innovants, ne soyez pas timides, postulez !
I’m glad to announce the immediate availability of API Platform 2.2 beta 1. This is a huge release that comes with a lot of exciting features including (but not limited too):
ReactJS and Vue.js Progressive Web App generators integration (a React Native app generator is also available)
Revamped Docker containers for both PHP and JavaScript components, including out of the box support for HTTP2, HTTPS and a built-in invalidation-based cache mechanism using Varnish
The ability to deploy in seconds in any Kubernetes cluster
A new, super-easy, way to register filters through annotations
And literally dozens of developer experience, performance and quality improvements
V2.2 will definitely be the best version of API Platform, and is probably the most advanced “full-stack” solution to create API-driven projects. The paradigm shift introduced by this new version has been detailed in my talk during the SymfonyCon 2017.
It took 6 months and 483 commits from more than 60 contributors to craft this version. The documentation has also been dramatically improved, even if some work is still to do (upgrading the getting started guide and migrating all articles to the new Flex directory structure, finish to document some new features).
Thank you very much to all contributors of the project! You rock!
Let’s see more in depth all of these new features:
The New Distribution
The easiest way to get started with API Platform has always been to use the provided Docker setup. In version 2.2, the Docker configuration has been totally redesigned to fit with the new features provided by Symfony Flex and to integrate our JavaScript components.
Decompress the archive and open a terminal in the resulting directory
Run
docker-compose up
You get:
– An API skeleton following the Flex directory structure. Just add classes representing your public data model (see the example below) to get a working hypermedia and/or GraphQL web API.
The API is available in HTTP/2 and HTTPS thanks to the provided development proxy. It also automatically benefits from the API Platform’s built-in cache mechanism (the Varnish container is also provided). CORS headers are automatically configured. As you can see, the nice documentation is – of course – still available if you open the entrypoint in a browser.
To generate the PWA, the tool parses the API hypermedia description automatically generated in the Hydra format by the API component. This generator can work with any server exposing a Hydra documentation (done with API Platform or not).
– Last but not least, a dynamically generated admin for the API is also automatically available:
Like the client generator, the API Platform Admin component also leverages the Hydra documentation to automatically guess the structure of the data exposed by the API.
Because it is built on top of React and Admin On Rest (aka React Admin), the UI is fully customizable.
Your app is now up and running in a managed cluster! Read the related documentation to learn more about the Kubernetes support.
GraphQL Support
GraphQL is a query language for APIs designed by Facebook that is becoming a very popular alternative to the REST pattern. GraphQL support has been the most wanted feature for a while, it is now fully implemented!
The new GraphQL subsystem of API Platform now supports:
Yes, both GraphQL and REST formats can be used for the same entity! Thanks to API Platform’s hypermedia support, you can even run a GraphQL request, then apply REST operations to the retrieved resources using their IRIs! The best of both worlds.
Your GraphQL API is ready! Browse
https://localhost:8443/graphql :
There is a lot to say about the GraphQL support, how to use it in collaboration with REST and how to apply fine-grained configurations. I’ll write a follow-up post dedicated to it, stay tuned!
JSON API is a rising, well designed, hypermedia format. Unlike JSON-LD (the default format exposed by API Platform), it’s not a web standard; and it has less features but it is also simpler to learn and understand.
With API Platform 2.2, you don’t have to choose, you can have both! And even more because API Platform supports out of the box JSON-LD/Hydra, HAL, JSON API, YAML, XML, raw JSON and as we’ve seen just before, GraphQL.
The API Platform filtering system is very powerful. It contains a lot of built-in filters and can easily be extended. However, until now, it wasn’t really easy to configure: it was requiring to declare services manually.
Because Symfony Flex is all about service autowiring and autoconfiguration, simplifying the filters configuration was a top priority task.
Hopefully, Antoine Bluchet created a nice way to do it using annotations:
Nothing more! You can now filter the collection of organizations by the
name property, both with REST and GraphQL!
In addition to these main features, a lot of other configuration options and various improvements have been introduced. Read the full changelogs for more information:
If you have some existing API Platform projects, or if you want to give a try to the framework, please test this new version and report any problem on our GitHub issue tracker!
Since API Platform 2.2, the Symfony Thanks command is also shipped with API Platform. Thanks to this tool, you can send a star to all the PHP libraries you use in your project (including API Platform) by simply running:
docker-compose exec php composer thanks
If you want to learn API Platform, come to one of the workshops organized during these upcoming tech conferences:
Don’t miss the next opportunities to learn @ApiPlatform during a 1 day workshop: – « Creating and deploying API Platform apps on @platformsh » / @APIdaysGlobal – « Mastering the API Platform’s server component » / @symfony_live Paris (2 sessions) then Phantasialand
This nice tool allows to automatically and dynamically build a fully featured administration interface (CRUD, pagination, relations…) for any API supporting the Hydra hypermedia vocabulary (more formats supported soon, see at the end of this article). 0 line of code required!
For instance, create a new app with Facebook’s create-react-app, replace the content of src/App.js with the previous snippet and run yarn add @api-platform/admin. You’re done!
If you get an error related to multiple versions of React being loaded, just remove the react and react-dom packages from your project’s package.json and run yarn install again.
If you don’t have a JSON-LD / Hydra API yet, here is the code of the one I’ll use in the following examples. This API has been created using the API Platform’s distribution:
Yes, you just need those two tiny PHP classes to get a hypermedia API. Learn more about the API component by reading the getting started guide. But, really, any API with a Hydra documentation will do the job regardless of the server-side programming language.
Native Support for to-Many Relations
API Platform Admin supports to-one relations since its very first release. However it was mandatory to customize the component used for to-many relations. This isn’t the case anymore. Our API documentation parser gained support for cardinalities and can now extract them if the API documentation includes OWL’s maxCardinality properties.
If no cardinality is provided, the admin will use a to-many widget by default.
Thanks to this new feature, here is how the edition screen of the Person resource looks like this:
The admin is able to guess that the Person resource is related to many Greeting ones and use the appropriate Admin On Rest component.
Detection of More Schema.org’s Types (name, url and email)
API Platform Admin is able to guess the widget to use depending of the type of a resource’s property. It supports:
Numbers (http://www.w3.org/2001/XMLSchema#float and http://www.w3.org/2001/XMLSchema#integer ranges)
Dates (http://www.w3.org/2001/XMLSchema#date and http://www.w3.org/2001/XMLSchema#dateTime ranges)
In this new release, Admin also supports some types of the popular Schema.org vocabulary:
As shown in the previous screenshots (e.g. Greetings select box), if a property has the type http://schema.org/name, this property will be used instead of the ID when displaying this relation
If a property has the type http://schema.org/url, the URL will be clickable when displayed in the admin
If a property has the type http://schema.org/email, the HTML input will be of type email and a basic validation will occur (this was already working in v0.1)
Support for Read-only Resources
The version 0.1 wasn’t able to deal with read-only resource (no POST nor PUT operation). We have improved the API doc parser to support owl:equivalentClass properties. Now, if the API documentation provide those properties, the admin will be builded even if the resource is read-only (of course in this case you will only be able to browse resources, and not to edit them).
Easier and Deeper Customization
Morgan Auchedé did an excellent work to make the Admin fully and easily customizable. You can now override any generated React component by a custom one, or one from Admin On Rest, or from MUI React. You can just replace (or ad, or remove) a specific input or field. But you can also replace a whole list, a show view, a creation or edition form or a remove button.
Here is an example of full customization, courtesy of Morgan:
The parser has been designed to be able to be parse other formats such as a GraphQL schema or Swagger/Open API. The api-doc-parser library provides an intermediate representation that is populated by the specific format parser. It’s this representation that is used by the parser as well as by our React and Vue.js Progressive Web App generator.
It means that when converters from other formats than Hydra to this intermediate representation will be available (Pull Requests welcome), both tools we’ll support those formats. As you may know, the server part of API Platform now supports GraphQL. You can guess which format we’ll implement next in the api-doc-parser!
API Platform is a framework designed to make the creation of API-based information systems easier. It provides server-side tooling to create modern hypermedia and Linked Data APIs in just a few minutes. This new version introduces client-side tools to bootstrap Single-Page Applications using ReactJS by consuming the autogenerated documentation of the API.
The changelog is huge, more than 200 commits by dozens of developers have been merged. I think we can say that this release will be great!
Let’s review the most interesting new features. If you just want to try it, the demo has been upgraded to use this new version and you can download it on GitHub.
It means that any API Platform API can now have an admin for free! The admin is fully customizable, a follow up post will come.
A React/Redux Webapp Generator
The admin is dynamic, no code generation happens. But sometimes it’s interesting to be able to generate some code to bootstrap a project. It’s exactly what the new api-platform-generate-crud tool does. It parses the Hydra documentation and generates a basic ReactJS webapp with the following features:
generation of the suitable HTML5 input type (number, date…) according to the type of the API property
display of the server-side validation errors under the related input (if using API Platform Core)
client-side validation (required attributes)
the generated HTML is compatible with Bootstrap and includes mandatory classes
the generated HTML code is accessible to people with disabilities (ARIA support)
the Redux and the React Router configuration is also generated
Thanks to Piotr Synowiec for his contributions and fixes to those frontend tools!
Builtin HTTP Cache Invalidation System
Exposing a hypermedia API has many advantages. One of them is the ability to know exactly which resources are included in HTTP responses created by the API. We used this specificity to make API Platform apps blazing fast.
When the new cache mechanism is enabled, API Platform collects identifiers of every resources included in a given HTTP response (including lists, embedded documents and subresources) and returns them in a special HTTP header called Cache-Tags.
A cache reverse proxy supporting cache tags (Varnish, CloudFlare, Fastly…) must be put in front of the web server and store all responses returned by the API with a high TTL. When a resource is modified, API Platform takes care of purging all responses containing it in the proxy’s cache. It means that after the first request, all subsequent requests will not touch the web server, and will be served instantly from the cache. It also means that the content served will always be fresh, because the cache is purged in real time.
The support for most specific cases such as the invalidation of collections when a document is added or removed or for relationships and inverse relations is built-in.
We also included Varnish in the Docker setup provided with the distribution of API Platform, so this new feature works out of the box.
Integration with Varnish and the Doctrine ORM is shipped with the core library. You can easily implement the support for any other proxy or persistence system.
A detailed blogpost about this feature will follow.
Per Resource Authorization Mechanism
Thanks to the API Platform’s events and the extension system, it was already easy to configure basic authorization rules. In the version 2.1, we introduced an easy way to configure fine grained authorization rules directly from resource classes.
In the following example, only the logged in admins can access all operations related to the SecuredResource. However, regular users owning a specific resource can also access it:
Under the hood, this new feature uses Symfony’s access control expressions. The object variable value is the current resource (or collection of resources) while the user variable contains an instance of the Symfony’s user currently logged in.
Subresources Support
Having the ability to expose subresources was one of the most requested features. It was already possible to use such URL patterns thanks to custom operations, but it was a bit complicated to do.
Fortunately Antoine Bluchet rolled up this sleeves and did an excellent job! As of API Platform 2.1, subresources are a first class citizen:
PHP
1
2
3
4
5
6
7
8
9
/**
* @ApiResource
*/
classProduct{
/**
* @ApiSubresource
*/
public$reviews;
}
The previous snippet is enough to expose through
http://example.com/products/1/reviews the list of RelatedDummies resources related to the Dummy #1.
The documentations will also reflect the availability of this new URL.
New Filters
API Platform comes with 3 new useful filters that you will love.
property_filter
Baptiste Meyer contributed 2 of them. The first one,
api_platform.serializer.property_filter, lets the client specify which properties the API must return.
When a resource is configured to use it, you can use the URL
/products/1?properties[]=price&properties[]=currency to only serialize the properties “foo” and “bar” of this entity (all other properties will be ignored).
It’s also possible to list the properties of embedded resources with the following format:
/products/1?properties[]=price&properties[brand][]=name.
group_filter
The second one,
api_platform.serializer.group_filter is similar, but instead of choosing properties one by one, you can pass a list of serialization groups to apply using a URL like:
/products/1?groups[]=detailed.
Those two filters allow to easily reduce the size of the returned resources to only include relevant data.
exists_filter
The last new filter,
api_platform.doctrine.orm.exists_filter, was contributed by Teoh Han Hui. It allows to filter a collection on the existence of a specified value:
/products?brand[exists]=0.
A Revamped API Doc UI
API Platform has a nice UI built with Swagger UI that is available for every URL of the API when requesting it from a browser (or any client sending a
Accept:text/html HTTP header). In API Platform 2.1, we upgraded Swagger UI to its new major version (3.0), a full rewrite in ReactJS (API Platform + React = ❤️) including a bunch of UX improvements.
Laury Sorriaux took this opportunity to propose a great custom stylesheet improving the overall user experience and respecting our color scheme. It also contains an animation featuring our cute spider (he will get a name soon, stay tuned)!
Last but not least, Daniel Kiesel contributed to improve the integration with OAuth (and FOSOAuthBundle): it’s now possible to login with OAuth from the UI by just adding a few lines of config.
Brand New Docker Setup
One of the coolest features of API Platform 2 was the ability to run the app locally by just typing
docker-compose up and to deploy apps in a breath with Kubernetes or Docker Swarm.
In API Platform 2.1, we dramatically improved the Docker support:
All images are now using Alpine Linux (reduce the size, improve the security)
Nginx and PHP-FPM are now used instead of Apache and mod_php
Varnish has been added (see the section about the cache invalidation mechanism)
The Docker Compose file has been upgraded to the format v3
Many compatibility problems with Windows have been fixed
The performance when using Docker for Mac or Docker for Windows has been dramatically improved
This Docker setup supports any Symfony-based application. Just copy/paste it in your Symfony project.
Improving the Docker configuration was a hard and collaborative work. I want to especially thanks Jacques Lefebvre, Teoh Han Hui and Antoine Bluchet for the large numbers of hours they spent to make this possible.
Integration in Symfony Flex
You can’t have missed it, Symfony 4 will come with an exciting tool to install and manage your projects: Symfony Flex. API Platform is already officially supported by Flex and can’t be easier to install: just type
composer req api
Fabien Potencier (the creator of Symfony) recorded a screencast showing how API Platform and Flex fit well together:
Impressive isn’t it? Flex only works with API Platform 2.1+. Older versions aren’t supported.
Of course, many other new features, fixes and improvements (especially regarding performance) have been merged, you can read the full changelog to learn more.
Next steps before the stable release:
Testing, testing and testing again. Please try the new features, upgrade your existing projects and run your tests suites against this new version! Report any problem on GitHub. It’s very very helpful to us!
Update the documentation and write new articles for the new features. They are already many pull requests opened, reviewing and improving them is much appreciated.
Learn how to use API Platform and Symfony to create super easily rich web and mobile applications relying on React (JS) for their presentational layer.
In just a few minutes, we will create a hypermedia API thanks to API Platform, Symfony and Doctrine. We will do it step by step, and the API will be 100% functional with support for pagination, validation, filters, resources embedding. The API will be automatically documented using Swagger and Hydra and beautiful user interface for developers will be available. HTTP cache, authorization and authentication can then be added in a breath.
Then, we will introduce all new client-side tools for API Platform:
A fully featured JavaScript (Single Page App) administration system with a modern user interface (Material Design) ; built on top of Admin On Rest (React and Redux). This admin is builded dynamically thanks to the API discoverability (Hydra).
A raw React, Redux and React Router code generator to bootstrap fully-featured Single Page Applications and native mobile apps thanks to the API documentation exposed by API Platform (client-side and server-side validation, on fields error, Twitter Bootstrap compatibility, a11y support…)
I’m pleased to announce the release of DunglasTodoMVCBundle 1.1.0.
DunglasTodoMVCBundle is an implementation of TodoMVC, the popular site providing the same todo app implemented in a ton of different JavaScript frameworks.
All dependencies including but not limited to Symfony, FOSRestBundle, JMSSerializerBundle, Backbone.js and Chaplin.js have been upgraded to their latest stable version
The code of the project has been updated accordingly
Client-side, a SPA built with Google’s AngularJS consuming the REST API provided by the server with Restangular or a similar library.
These components share the same philosophy (built on top of dependency injection and MVC-like patterns, designed to be intensively tested) and play very well together.
This stack allows to create awesome blazing-fast web applications. Better, the client part and the server part of the app are loosely coupled, can evolve separately and can even be maintained by different teams.
However, this kind of apps often suffer of security problems, and especially Cross-site Request Forgery (CSRF or XSRF) vulnerabilities.
This bundle provides out of the box CSRF protection for AngularJS apps interacting with a Symfony-backed app.
Despite it’s name, it does not depend of AngularJS and can also be used with Chaplin.js / Backbone.js, jQuery or even raw JavaScript. To do so, install and configure the bundle, then just add to XHR requests a HTTP header called X-XSRF-TOKEN containing the value of the token set by a cookie on the first HTTP request. The bundle will automatically check the validity of the provided token. If it is not valid, an Access Denied error (HTTP 401) will be thrown.
The bundle is fully tested with phpspec and obtain a platinum medal on the brand new (awesome) SensioLabs Insight quality monitoring system.
Internals documentation and installation instructions are provided on the GitHub page of the bundle. Check it, test it, star it and tell me what you think of it!
Je viens de publier un petit plugin jQuery sous license MIT qui affiche une demande de confirmation lorsqu’un l’utilisateur quitte une page web après avoir rempli un formulaire sans l’avoir envoyé.
Perdre toutes les données que l’on vient de saisir en cliquant sur un lien ou en fermant la fenêtre sans avoir appuyer sur “Envoyer”, c’est le genre de détails qui font rager contre les applications web mal finies.
Plus d’excuse avec jquery.confirmExit. Cerise sur le gâteau, le plugin supporte tous les nouveaux champs de formulaires introduits avec HTML5.
Yeah, it’s the first public release of the new syntax highlighter announced in my previous post !
Ajax Syntax Highlighter is a small Javascript utility designed to highlight code embed in a web page in a semantic and standard compliant way.
It automatically looks for source code in the page, send it to a server-side highlighter and display the highlighted code. It also has a “view as plain text” feature and internationalization (French translation available).
Ajax Syntax Highlighter is built with Yahoo! UI and uses JSON for serialization.
It currently includes GeSHi as server-side (PHP required) highlighter but it can be easily used with others such as Pygments.
As you can see, the current graphics come from SyntaxHighlighter and are not so good. If you have some webdesign skills and can help me to enhance it, please contact me !
