Summary

Auto-route base is a skeleton for creating custom auto routing capabilities. Retrieves code automatically.

Installation

Install with npm:

npm install --save autoroute-base

Project Status

• Stable/Release
• Active (June 26, 2015)

Example

See the test for a simple example.

autoroute-express-promise example (in TypeScript - to see a vanilla JavaScript example see below).

import {createAutoRoute, method as method_} from 'autoroute-base'
import _ = require('lodash')

const toControllers = _.curry(({message, baseRoute, sendWrapper, routeName}: AutoRouteExpressPromise.ToControllersOptions, controllerMethod: AutoRouteExpressPromise.ControllerMethod) => {

    const [routeMethodIndex, baseController] = controllerMethod,
          methodName = method_[routeMethodIndex], // named route method
          messageInfo = {routeName: routeName, methodName: methodName}

    // Wrap base controller in express style callback.
    baseRoute[methodName]((request: any, client: any, error: any) => {

        message.call(messageInfo, messageInfo)

        var send = <any> _.compose(client.send.bind(client), sendWrapper)

        baseController(request).then(send).catch(error).done()
    })

})

const createRoutes = _.curry((o: AutoRouteExpressPromise.Options, routeDefinitions: AutoRouteExpressPromise.RouteDefinition[]) => {
    _.forEach(routeDefinitions, routeDef => {
        const {route, methods} = routeDef,
              startRoute = o.baseRoute(route), // Get router
              options_: AutoRouteExpressPromise.ToControllersOptions = <any> _.assign({}, o, {routeName: route, baseRoute: startRoute})
        _.forEach(methods, toControllers(options_)) // attach routes/methods to router
    })
})

export const routes = _.curry((options: AutoRouteExpressPromise.Options, glob: string[]) => {
    createAutoRoute({createRoutes: createRoutes(options), glob: glob})
})

export const method = method_

Vanilla JavaScript example of above.

var autoroute_base_1 = require('autoroute-base');
var _ = require('lodash');
var toControllers = _.curry(function (_a, controllerMethod) {
    var message = _a.message, baseRoute = _a.baseRoute, sendWrapper = _a.sendWrapper, routeName = _a.routeName;
    var routeMethodIndex = controllerMethod[0], baseController = controllerMethod[1], methodName = autoroute_base_1.method[routeMethodIndex], messageInfo = { routeName: routeName, methodName: methodName };
    // Wrap base controller in express style callback.
    baseRoute[methodName](function (request, client, error) {
        message.call(messageInfo, messageInfo);
        var send = _.compose(client.send.bind(client), sendWrapper);
        baseController(request).then(send).catch(error).done();
    });
});
var createRoutes = _.curry(function (o, routeDefinitions) {
    _.forEach(routeDefinitions, function (routeDef) {
        var route = routeDef.route, methods = routeDef.methods, startRoute = o.baseRoute(route), options_ = _.assign({}, o, { routeName: route, baseRoute: startRoute });
        _.forEach(methods, toControllers(options_)); // attach routes/methods to router
    });
});
exports.routes = _.curry(function (options, glob) {
    autoroute_base_1.createAutoRoute({ createRoutes: createRoutes(options), glob: glob });
});
exports.method = autoroute_base_1.method;

API

import {createAutoRoute, method} from 'autoroute-base'

createAutoRoute(options)

where options:

{
    glob: string[]
    _globOptions?: any
    createRoutes?: (postGlobResult: any) => any
}

glob: (Required) Array of globs for files to grab. E.g., ['./controllers/**/index.js']. autoroute-base uses a custom post parse to get back the route/controllers in a cleaner manner for easy processing, assuming you are using the same set up I used.

_globOptions: (Optional) Options used in require-glob. Note, to override the autoroute-base reducer behaviour do {reducer: null} (changes to native behaviour) or {reducer: CustomReducer}.

createRoutes: (Optional) After grabbing all the files to use. It is time to process them for your custom project. Do your post processing here. This will use the result of the require-glob.

method

This is an enumeration of all the express.js methods:

get, post, put, head, delete, options, trace, copy, lock, mkcol, move, purge, propfind, proppatch, unlock, report, mkactivity, checkout, merge, "m-search", notify, subscribe, unsubscribe, patch, search, connect

E.g.,

method.get // => 0
method[0] // => "get"
