RAML to HTML documentation generator


A simple RAML to HTML documentation generator, written for Node.js. Check raml2md for a RAML to Markdown generator.

npm i -g raml2html
raml2html --help
raml2html example.raml > example.html
raml2html -t examples/custom-template-test/template.nunjucks -i example.raml -o example.html
const raml2html = require('raml2html');
const configWithDefaultTemplates = raml2html.getDefaultConfig();
const configWithCustomTemplates = raml2html.getDefaultConfig('my-custom-template.nunjucks', __dirname);
// source can either be a filename, url, or parsed RAML object 
raml2html.render(source, configWithDefaultTemplates).then(function(result) {
  // Save the result to a file or do something else with the result 
}, function(error) {
  // Output error 
 * config should be an object with at least an `processRamlObj` property which is a function that receives the raw RAML 
 * object and must return a promise with the result. You can do whatever you want in this function.
 * You can also supply a postProcessHtml function that can for example minify the generated HTML.
raml2html.render(source, config).then(function(result) {
  // Save the result to a file or do something else with the result 
}, function(error) {
  // Output error 

If you only want to configure the default Nunjucks environment you don't have to override the entire processRamlObj function. Just get the default config (const config = raml2html.getDefaultConfig();) and add a setupNunjucks function to it that takes env as its only parameter.

See also example/script.js for an example of using raml2html as a library.

Please note that if you want to use a different template language, you're probably better off directly using raml2obj.

You can use the latest raml2html directly from Gulp, or use the third party gulp-raml2html plugin (which uses an outdated version of raml2html).

There's a third party Grunt plugin at

Please see for a live example.

raml2html 4 and higher only support RAML 1.0 files. Please stick with raml2html 3.x for RAML 0.8 support.

If you get parsing errors, please do not report them to raml2html: it doesn't do the actual RAML parsing. Review the error and fix your RAML file, or open a new issue at raml-js-parser.
