Protagonist is a Node.js wrapper for the Snow Crash library.
API Blueprint is Web API documentation language. You can find API Blueprint documentation on the API Blueprint site.
The best way to install Protagonist is by using its NPM package.
$ npm install protagonist
Works smoothly with node.js ~0.8.15, 0.10.x, 0.12.x and iojs v1.x.x
var protagonist = require('protagonist');
protagonist.parse('# My API', function(error, result) {
if (error) {
console.log(error);
return;
}
console.log(result.ast);
});
If you for some reason need to use the api synchronous, that is also possible. Please note that the recommended way is to use the asynchronous api as to not block the event loop.
var result = protagonist.parseSync('# My API');
Parsing this blueprint:
# GET /1
+ response
will produce the following object (result
variable):
