@naveen.agarwal/express-scaffold NPM

express-scaffold

This package will provide scaffold functionality similar to rails scaffold generator which can be used to create the controller, model, service, middleware, and migration.

Note: This is an extention to sequelize-cli package, hence will only work to support sequelize ORM for now.

How to use?

Set the controllers, models, and services path in your .sequelizerc file

Step 1.

const path = require('path');

module.exports = {
  'controllers-path': path.resolve('app', 'controllers'),
  'models-path': path.resolve('app', 'models'),
  'services-path': path.resolve('lib', 'services'),
  'middlewares-path': path.resolve('lib', 'middlewares')
}

Step 2.

npm install --save-dev @naveen.agarwal/express-scaffold
npx sequelize-cli init
npx scaffold  --force --name User --attributes firstName:string,lastName:string
// above command syntax is same as sequelize-cli model creation syntax
npx sequelize-cli db:migrate

The above command will generate the following files:

app/models/user.js
migraitons/{TimeStamp}-create-user.js
app/controllers/user-controller.js
lib/services/base-service.js // if not already exists
lib/services/user-service.js
lib/middlewares/user-middleware.js

Step 3.

Mount it in your main routing file o index.js/app.js

const express = require('express')
const app = express()
const user = require('./app/controllers/user-controller');
app.use('/users', user);

Update Strong params has been added. In order to make it work please ensure you have strong params added in your application. If not then you can add it by running following commands:

npm i --save strong-params

// and then add the strong params middleware in your application index/app js file.
const params = require('strong-params');
app.use(params.expressMiddleware());

Swapper specs OpenAPI(2.0)

Now along with CRUD APIs, it generates the swagger specs as well. There will be a folder named api-specs which will caontain swagger.json file. Use this file with swagger-ui-express.

Mount it in nodejs server file, usually either index.js or app.js

const swaggerUi = require('swagger-ui-express');
const swaggerDocument = require('./api-specs/swagger.json');

app.get('/', (req, res) => res.send('Hello World!'))
app.use('/api-docs', swaggerUi.serve, swaggerUi.setup(swaggerDocument));

visit /api-specs from your web browser to see the specs generated.

Note: if you use the --force option then it will regenrate the swagger specs as well along with controller and other code.
