express-dump-curl

This ExpressJS middleware dumps the equivalent curl command of the request received.

The curl dump can be written in standard output or on a specific file and it is generally very well formatted to ease both reading and editing.

Installation

Install the package by running one of the following commands, depending on your configuration:

npm install --save express-dump-curl

yarn add express-dump-curl

Usage

1. Include the package in your ExpressJS app along with other dependencies.

const fs = require ( 'fs' );
const express = require ( 'express' );

// Include express-dump-curl as a dependency
const dump_curl = require ( 'express-dump-curl' ).dump_curl;

const app = express ();
...

2. Declare this as a middleware just above the route definitions

app.use ( bodyParser.json() );
app.use ( multiplart() );
...

// There are two parameters you can pass at the `dump_curl()` middleware:
//
// dump_curl ( output_file,  force_https )
//
// - output_file   - a complete filepath where to save the curls.
//                  if the path is not specified, stdout will be used.
//
// - force_https   - a flag T/F. If true, the protocol of the CURL will always
//                   be "https" reguardless of the real protocol used.

// Include the express dump curl middleware
// if no filename is specified in the call, console.log will be
// used to dump curls
app.use ( dump_curl () );

// Alternatively, you can specify a filename in dump_curl definition
// app.use ( dump_curl ( "/ramdisk/curls.txt" ) );

...
app.use('/auth', authRouter);
app.use('/users', usersRouter);

From now on, every single call will be logged on console or file depending on your configuration.

There are two parameters you can pass at the dump_curl() middleware:

dump_curl ( output_file, force_https )

• output_file - a complete filepath where to save the curls. if the path is not specified, stdout will be used.

• force_https - a flag T/F. If true, the protocol of the CURL will always be "https" reguardless of the real protocol used.

Additional APIs

You can do even more with this module, in fact there are two extra methods you can use in your software.

dump_restest ( output_file, force_https )

Is identical to dump_curl() but it dumps a JSON in RESTest format (the RESTest application has not been delivered yet).

curl_str ( force_https ) returns a string with the CURL. The method is the same used inside dump_curl()
