Express route generator

CLI tool to create new endpoints / routes in an Express application.

Installation

npm install -g @kmpizmad/express-route-generator

Keep in mind, that due to maintenance it's better to use it from the npm registry like this: npx @kmpizmad/express-route-genertor

Commands

add | a [options] <name>: adds a new route under the provided path remove | rm [options] <name>: removes a route by folder name list | ls [options]: lists all routes

Options

add:

-p, --path [string] -s, --schemes [string] --typescript [string] --no-test [boolean] -m, --methods [array]

remove:

-p, --path [string] -t, --test [boolean]

list:

-p, --path [string] -r, --recursive [boolean]

All of the above can be defined though an erg.config.js or erg.config.json file

Options Reference

-t, --test [boolean]

Default: false

Removes the test file only.

Example:

// erg rm myRoute --test

routes
└ myRoute
  └ index.js
  └ myRoute.handlers.js

-r, --recursive [boolean]

Recursively lists every route.

Example:

myRoute
  └ index.js
  └ myRoute.handlers.js
  └ myRoute.test.js
myRoute2
  └ index.js
  └ myRoute2.handlers.js
  └ myRoute2.test.js
myRoute3
  └ index.js
  └ myRoute3.handlers.js
  └ myRoute3.test.js

Default: false

Configuration

rootDir [string] schemesDir [string] language [string] test [boolean] methods [array]

Configuration Reference

rootDir [string]

Default: undefined

Path to the folder where the routes are stored. Equivalent of -p, --path <path>.

Examples:

• rootDir: ./server/routes
• rootDir: ./server/api/endpoints

schemesDir [string]

Default: undefined

Path to the folder where the custom schemes are stored. Equivalent of -s, --schemes <path>.

Examples:

• schemesDir: ./schemes
• schemesDir: ./server/routes/schemes

language [string]

Default: javascript

Defines the extension of the files. Equivalent of --typescript.

Available values:

• javascript
• typescript

Example:

// language: 'javascript'

routes
└ myRoute
  └ index.js
  └ myRoute.handlers.js
  └ myRoute.test.js

test [boolean]

Default: true

Defines if a test file should be generated. Equivalent of --no-test.

Example:

// test: false

routes
└ myRoute
  └ index.js
  └ myRoute.handlers.js

methods [array]

Default: undefined

Defines what methods should be handled by the router. Equivalent of -m, --methods <methods...>.

Available values:

• get
• getOne
• post
• put
• putOne
• patch
• patchOne
• delete
• deleteOne

// methods: ['get', 'getOne']

routes
└ myRoute
  └ index.js
  └ myRoute.handlers.js

Custom Schemes

ERG provides an opportunity to create your own schemes. The location must be defined otherwise it'll use the built-in schemes.

Filenames must contain the follows:

index: This will be the router .handlers: This will contain the handlers for the router .test: This will be the test

Prefixing and suffixing is doable, because the result will always start with the route name and end with the extension.

// Example - erg add testRouter --path routes --schemes mySchemes

mySchemes
└ sample.index.ts
└ sample.handlers.ts
└ sample.test.ts

// Result

routes
└ testRouter
  └ index.js
  └ testRouter.handlers.js
  └ testRouter.test.js

Examples

// Example structure

root
└ src
  └ server
  └ db
  └ middlewares
  └ routes
  └ utils

// Example config

module.exports = {
  rootDir: "src/server/routes",
  methods: ["get", "getOne"]
}

// Example output of 'erg add generatedRoute'

root
└ src
  └ server
  └ db
  └ middlewares
  └ routes
    └ generatedRoute
      └ generatedRoute.handlers.js
      └ generatedRoute.test.js
      └ index.js
  └ utils

// generatedRoute.handlers.js

export const getHandler = async (req, res, next) => {};
export const getOneHandler = async (req, res, next) => {};

// generatedRoute.test.js

import supertest from "supertest";

describe('generatedRoute test', () => {
  it('get', async done => {
    const response = await supertest(server).get('/generatedRoute');
    // Expectations
    done();
  });
  it('getOne', async done => {
    const response = await supertest(server).get('/generatedRoute');
    // Expectations
    done();
  });
});

// index.js

import { Router } from 'express';
import { getHandler, getOneHandler } from './generatedRoute.handlers';

const router = Router();
router.route("/").get(getHandler)
router.route("/:id").get(getOneHandler);

export default router;
