express-suite

A collection of Middlewares for Express

:) More middlewares will be available as the time progresses.

Installation

$ npm i express-suite

routeCheck

This middleware will handle all requests to non-registered routes for you.

In the config option, you can specify a route to handle all requests to non-existing routes. For example, a custom page-not-found notice.

If no config option is passed, the middleware will send a 404 to those requests.

//Dependencies
const express = require('express');

//Require the routeCheck Middleware
const { routeCheck } = require('express-suite');

//Initialize the App
const app = express();

//Load Routes
const example = require('./routes/example');

//Use Routes
app.use('/', example);

//The routeCheck middleware config option
//The redirectPath refers to the custom route you want to redirect the requests to
const options = { redirectPath: '/PnF' };

//It's important to use the routeCheck middleware after all routes are loaded
app.use(routeCheck(app, options));

//Start the server
app.listen(5003);

emptyInputCheck

This middleware checks for all empty inputs to all routes (unless used at a router level) by checking the body of both POST and GET requests.

Note: 0 does count as a valid input.

Default Error Messages:

1. Requests with an empty body will be met with a 400 and the message:

{
  msg: 'The request body is empty!';
}

2. Request with empty fields in the body will be met with a 400 and the message:

{
  msg: 'The request body is empty!',
  field:'key of the missing field'
}

//supressFieldKey=true
{
  msg: 'The request body is empty!',
}

You can specify the middleware to skip the check for GET requests in the config option.

Custom error message for each scenario above and whether to supress the filed key can be specified like the example below:

//Dependencies
const express = require('express');
const bodyParser = require('body-parser');

//Require the routeCheck Middleware
const { emptyInputCheck } = require('express-suite');

//Initialize the App
const app = express();

//bodyParser Middleware
app.use(
  bodyParser.json({
    limit: '5mb',
    extended: true,
  }),
);

//The emptyInputCheck Middleware
//It's important that we place the emptyInputCheck Middleware after the bodyParser middleware
//Make sure you call the emptyInputCheck middleware before the routes are loaded
app.use(
  emptyInputCheck({
    checkGet: true, //Wether to check the GET requests or not
    emptyBodyMsg: 'Err Msg 1', //Custom msg for empty body
    emptyFieldMsg: 'Err Msg 2', //Custom msg for missing fields
    supressFieldKey: false, //To supress the key of the missing field
  }),
);

//Load Routes
const example = require('./routes/example');

//Use Routes
app.use('/', example);

//Start the server
app.listen(5003);
