express-body-formatter

An express middleware that formats the request body to a particular unified style

Installation

Using npm

npm install --save express-body-formatter

Using yarn

yarn add express-body-formatter

Usage

const express = require("express");
const bodyParser = require("body-parser");
const bodyFormatter = require("express-body-formatter");
const app = express();

app.use(bodyParser.json());
const options = { exclude: ["name"], trim: true, transform: "lowerCase" }
app.use(bodyFormatter(options));
app.use("/", function(req, res) {
  res.json(req.body);
});

app.listen(3000);

if a json object is sent to the server, for example:

{"name": "John Doe ", "status": " I love programmING "}

your object will become:

{name: "John Doe ", "status": "i love programming"}

name will remain the same because it was inluded in the exclude array option but status will be formatted accordingly

Options

all options are optional, to use the default options, you can either send an empty object as an argument or not send an arguement at all
