var books = new fake.Resource("Book")
  .add({

    year: 2009 })
  .add({
    name: "Public Enemies",
    author: "Bryan Burrough",

  });

var server = new fake.Server()

introduction

you hold in your hands an extremely simple fake API server built in Node.js and aptly named fake-api-server. this little project came about after I wrote a comment on this HN thread responding to an article by Jeremy Morgan about implementing the same thing on a "self-hosted" .NET server.

since the crux of that article was that you want the fake API to get out of the way so you can focus on front-end development, it seemed prudent to rewrite the code in JavaScript to avoid context-switching between languages.

dependencies

• node
• express

api reference

the API is made up of two types: Resource and Server. you create a number of resources which you then register with a server. the server listens for requests to /api routes and handles the various registered resources RESTfully.

any method that doesn't otherwise return a value returns the object itself to allow for method chaining.

###Resource###

new Resource(name)

• creates a new resource with the given name, which should be in singular form. the name will be pluralized for the api (see the documentation for pluralName).

idAttribute([newVal])

• gets or sets the id attribute name, which defaults to id.

idFactory([newVal])

• gets or sets the new record id factory. this should be a method that returns a novel unique id each time it's called.

name([newVal])

• gets or sets the name of the resource.

pluralName([newVal])

• gets or sets the plural name of the resource, which defaults to the name plus "s".

all()

• get all records for this resource.

add(record)

• add a record to the resource data store. the id attribute will be automatically set. the record is not copied, so if you need the new id you can get it from the object reference passed in.

find(id)

• finds a record by id.
• this method, update and remove return false if the id is not found for this resource.

update(id, updates)

• update a record by id, returning the updated record.

remove(id)

• remove a record by id, returning a boolean indicating success.

###Server###

new Server()

• creates a new server.

listen([port=3000])

• starts listening for REST requests on the given port.

register(resource)

• register a given resource for the API. the appropriate REST verbs will be routed.
