restify-enroute

This module provides configuration driven route installation for restify. Instead of having to declare routes in code, you can create a configuration file like this:

{
    "schemaVersion": 1,
    "routes": {
        "foo": {
            "get": {
                "source": "./test/etc/fooGet.js"
            },
            "post": {
                "source": "./test/etc/fooPost.js"
            },
            "put": {
                "source": "./test/etc/fooPut.js"
            },
            "delete": {
                "source": "./test/etc/fooDelete.js"
            },
            "head": {
                "source": "./test/etc/fooHead.js"
            },
            "patch": {
                "source": "./test/etc/fooPatch.js"
            },
            "options": {
                "source": "./test/etc/fooOptions.js"
            }
        },
        "bar": {
            "get": {
                "source": "./test/etc/barGet.js"
            },
            "post": {
                "source": "./test/etc/barPost.js"
            }
        }
    }
}

This declares the route name, http method, and handler file on disk. this module will install these routes onto a restify server for you. The corresponding handler file would look like:

module.exports = function handler(req, res, next) {
    res.send(200, 'Hello World');
    next()
};

API

Synopsis: install(opts, cb)

Installs routes as defined in opts into a restify server, invokes the callback when done.

• opts: The options object containing
  • opts.server The restify server to install the routes on to.
  • [opts.config] The POJO of the enroute config.
  • [opts.basePath] Used with [opts.config]. The POJO requires a basePath to correctly resolve the route source file(s).
  • [opts.configPath] The path to the enroute config on disk.
  • [opts.hotReload] Indicate whether you want the server to reload the route from disk each time a request is served, defaults to false
  • [opts.excludePath] The relative path to the basepath to exclude reloaded routes
• cb The callback. Returns Error if there's an error installing the routes.

Note only one of opts.config or opts.configPath is needed. The module will either read in the file from disk, or use a pre-populated POJO.

opts.hotReload allows the restify server to reload the route from disk each time the request is processed. This is extremely slow and should only be used in non-production instances.

Example

const enroute = require('restify-enroute');
const restify = require('restify');

const CONFIG = {
    schemaVersion: 1,
    routes: {
        foo: {
            get: {
                source: './test/etc/fooGet.js'
            },
            post: {
                source: './test/etc/fooPost.js'
            },
            delete: {
                source: './test/etc/fooDelete.js'
            },
            head: {
                source: './test/etc/fooHead.js'
            },
        }
    }
};

const server = restify.createServer();
// install routes with enroute
enroute.install({
    config: CONFIG,
    server: server,
    basePath: __dirname
}, function (err) {
    if (err) {
        console.error('unable to install routes');
    } else {
        console.log('routes installed');
        SERVER.listen(1337);
    }
});

Synopsis: validate(opts, cb)

Parse and validate a enroute config. This will verify that the config is valid and return a POJO with the properties. Note only one of opts.config or opts.configPath is needed.

• opts The options object containing
  • [opts.config] The POJO of the config you want to validate.
  • [opts.configPath] The path to the config on disk to validate.
• cb The callback f(err, validatedConfig). Returns Error if there's an
• error parsing or validating the config

Example

const enroute = require('restify-enroute');

const CONFIG = {
    schemaVersion: 1,
    routes: {
        foo: {
            get: {
                source: './test/etc/fooGet.js'
            },
            post: {
                source: './test/etc/fooPost.js'
            },
            delete: {
                source: './test/etc/fooDelete.js'
            },
            head: {
                source: './test/etc/fooHead.js'
            },
        }
    }
};

const server = restify.createServer();
// install routes with enroute
enroute.validate({
    config: CONFIG,
    basePath: __dirname
}, function (err) {
    if (err) {
        console.error('unable to install routes');
    } else {
        console.log('config successfully validated');
    }
});
