This document provides an introduction and overview of Representational State Transfer (ReST). It discusses the history of ReST and how it was rediscovered by Roy Fielding. It also explains some key aspects of ReST including how it uses HTTP verbs like GET, POST, PUT, and DELETE on URLs to perform CRUD operations on resources. The document provides examples of ReST implementations on Twitter and Facebook. It also offers guidance on best practices for designing ReST APIs and includes some relevant quotes about ReST.

ReST - History ¡ñ Representational State Transfer ¡ñ ReST was re-DISCOVER-ed by Roy Fielding ¡ñ Doesnt require any external library ¡ñ Tightly bond with HTTP
ReST ¨C HTTP Client Send Request Server Send Response GET / HTTP/1.1 Host: xkcd.com HTTP/1.1 200 OK Accept: text/html Date: Sat, 02 Apr 2011 21:05:05 GMT User-Agent: Mozilla/5.0 Server: lighttpd/1.4.19 (Macintosh) Content-Type: text/html <html>...</html>
ReST - HTTP HTTP Verb ¡ñ GET ¡ñ POST ¡ñ PUT ¡ñ DELETE Routes ¡ñ URL + HTTP Verb
ReST - Definition ¡°The Same Thing with a different STATE changes its meaning¡± ¡°The message is changed based on it's State¡±
ReST ¨C How To ¡ñ Loved by developer ¡ñ Easy to read, easy to understand, easy to learn
ReST Bad !! Imagine :) /getAllUsers /getMentions /getUserById /getUserTimeLine /getUsers /getHomeTimeLine /deleteUser /getStatusesRetweet /updateUser /updateStatuses /deleteUserTenYearsOld /destroyStatus /newUser /getRetweets /getUserUnderTenYearsOld
ReST - Quotes ¡°Web it's not about HTML pages, it's about resources, and those resources are located by URLs¡±
So ? ¡ñ We only need two base URLs as the location of a resource (collection of resource, and single resource) ¡ñ Resources is Noun, use Noun :) ¡ñ Plural is better Resource POST GET (READ) PUT DELETE (CREATE) (UPDATE) /users Create new List all Users Update All Delete All user Users Users /users/1 - Show User Update User Delete User (with ID = 1) with ID = 1 (if with ID = 1 Exist)
Association ? Easy :) GET /departments/1/users POST /departments/1/users PUT /users/123 DELETE /users/123
Query Use '?' for Query GET /users?limit=50&offset=100 GET /users?username=indra&birth=1990 GET /users?column=id,name,username,birth GET /users.json (/users.xml)
Versioning /v1/users/
