express-var-dump
The Express version of PHP's
var_dump(). It lets you
output information in JSON format regarding cookies, session data, query params,
route params, post data and request headers by default.
install
This is a Node.js module available through the
npm registry. Installation is done using the
npm install command:
npm install express-var-dumpusage
First add the view helper to your app:
// app.js
const { addVarDumpViewHelper } = require('express-var-dump');
const app = require('express')();
// ..define express middleware && other stuff before..
app.use(addVarDumpViewHelper);
// ..define express routing after..Then in your view call varDump() (using ejs templating engine below):
<!-- views/index.ejs -->
<html>
<body>
<%- varDump() %>
</body>
</html>Output:
advanced usage
varDump(arrayOfProperties, object): html
You can also use varDump directly to generate prettified JSON data to HTML
code for any object (in Express it defaults to the request object and the
properties detailed in the description).
const { varDump } = require('express-var-dump');
const packageData = require('./package.json');
console.log(varDump(['name', 'version', 'author', 'dependencies'], packageData));
// outputs HTML code generated with `pretty-print-json`That allows you to use the module with other Node.js web apps that don't use Express.
