How to quickly make REST APIs with CompoundJS
- 1. How to quickly make REST APIs
- 2. infos made by Anatoliy Chakkaev 1208 stars on github 1000+ commits previously named RailwayJS
- 3. based on top of ExpressJS Express is inspired by Sinatra: simple and light Express has cool stuff: middlewares, error handling, logging...
- 4. an express server express = require 'express' app = express() app.get '/hello', (req, res) -> res.end hello: 'world'
- 5. Neat but almost nothing is configured by default.
- 6. compound inspired by Rails: full featured and scaffolding quickstart compound init blog-api --coffee
- 7. configuration Load dependencies cd blog-api npm install Backend only: we remove UI rm -rf public app/assets app/views # remove code from config/environment.coffee - app.use compound.assetsCompiler.init() - app.set 'cssEngine', 'stylus' - app.use express.static ''#{app.root}/public'', maxAge: 86400000
- 16. models and JugglingDB ORM/ODM for Node.js Integrated with Compound adaptable to any data source validators relations
- 17. generator compound g model post title content published:boolean renders: # db/schema.coffee Post = describe 'Post', -> property 'title', String property 'content', String property 'published', Boolean # app/models/post.coffee module.exports = (compound, Post) → let's add this: Post.published = (callback) -> Post.all published: true, callback
- 18. controllers # app/controllers/posts_controller.coffee action 'create', -> Post.create body (err, post) -> if err then send 500 else send post, 201 action 'all', -> Post.all (err, posts) -> if err then send 500 else send posts action 'published', -> Post.published (err, posts) -> if err then send 500 else send posts
- 19. pre-processors and post-processors before -> Post.find params.id, (err, post) => if err then send 500 else if not post then send 404 else @post = post next() , only: ['show', 'update', 'destroy'] after -> console.log 'request processed' next()
- 20. That makes simpler controllers! action 'show', -> send @post action 'update', -> @post.updateAttributes body, (err) -> if err then send 500 else send 200 action 'destroy', -> @post.destroy -> if err then send 500 else send 204
- 21. routing helpers basic # config/routes.coffee map.get 'posts', 'posts#published' map.get 'admin/posts', 'posts#all' map.post 'admin/posts', 'posts#create' map.get 'admin/posts/:id', 'posts#show' map.put 'admin/posts/:id', 'posts#modify' map.del 'admin/posts/:id', 'posts#destroy' evolved # generate standard CRUD routes map.resources 'posts' # Link directly to controller with the right name map.all ':controller/:action' map.all ':controller/:action/:id'
- 22. namespaces map.get 'posts', 'posts#published' map.namespace 'admin', -> map.get 'posts', 'posts#all' map.post 'posts', 'posts#create' map.get 'posts/:id', 'posts#show' map.put 'posts/:id', 'posts#modify' map.del 'posts/:id', 'posts#destroy'
- 23. more generators for controllers Soon: custom generators Soon: custom structure + a lof of features if you want to make UIs
