Usage for NodeJS

Load

Loading a RAML file is as easy as follows:

  var raml = require('raml-parser');

raml.loadFile('myAPI.raml').then( function(data) { console.log(data); }, function(error) { console.log('Error parsing: ' + error); });

You can alternatively load from a string containing the api definition:

  var raml = require('raml-parser');

var definition = [ '#%RAML 0.8', '---', 'title: MyApi', 'baseUri: http://myapi.com', '/Root:' ].join('\n');

raml.load(definition).then( function(data) { console.log(data); }, function(error) { console.log('Error parsing: ' + error); });

The shape of the returned object is (unofficially) documented in this Typescript interface.

Abstract Syntax Tree

Generating an AST from a RAML file is as easy as follows:

  var raml = require('raml-parser');

var myAPI; raml.composeFile('myAPI.raml').then( function(rootNode) { console.log('Root Node: ' + rootNode) }, function(error) { console.log('Error parsing: ' + error); });

you can also alternatively generate an AST from a string containing the api definition:

  var raml = require('raml-parser');

var definition = [ '#%RAML 0.8', '---', 'title: MyApi', 'baseUri: http://myapi.com', '/Root:' ].join('\n');

raml.compose(definition).then( function(rootNode) { console.log('Root Node: ' + rootNode) }, function(error) { console.log('Error parsing: ' + error); });

Usage for In-Browser

Using the RAML parser from inside the browser requires the user to actually include the RAML javascript file in a script tag as follows:


from there on the usage is pretty much the same as NodeJS, the script defines a RAML.Parser object globally which can be used as follows:

RAML.Parser.loadFile('http://localhost:9001/myAPI.raml').then( function(data) {
  console.log(data)
}, function(error) {
  console.log('Error parsing: ' + error);
});

Notice that the in-browser version can fetch remote API definitions via XHR.
