@httptoolkit/HTTPSnippet

Part of HTTP Toolkit: powerful tools for building, testing & debugging HTTP(S)

Httpsnippet is an HTTP request snippet generator for many languages & tools including: cURL, HTTPie, Javascript, Node, C, Java, PHP, Objective-C, Swift, Python, Ruby, C#, Go, OCaml and more!

This library relies on the popular HAR format to import data and describe HTTP calls.

This is a fork of Kong's (previous Mashape's) httpsnippet library, which appears to no longer be maintained. This version is in active production use in HTTP Toolkit.

Install

# to use in cli
npm install --global @httptoolkit/httpsnippet

# to use as a module
npm install --save @httptoolkit/httpsnippet

Usage

  Usage: httpsnippet [options] <files ...>

  Options:

    -h, --help                output usage information
    -V, --version             output the version number
    -t, --target <target>     target output
    -c, --client [client]     target client library
    -o, --output <directory>  write output to directory
    -x, --extra [{"optionKey": "optionValue"}]  provide extra options for the target/client

Example

process single file: example.json in HAR Request Object format, or full HAR log format:

httpsnippet example.json --target node --client unirest --output ./snippets

$ tree snippets
snippets/
└── example.js

process multiple files:

httpsnippet ./*.json --target node --client request --output ./snippets

$ tree snippets/
snippets/
├── endpoint-1.js
├── endpoint-2.js
└── endpoint-3.js

provide extra options:

httpsnippet example.json --target http --output ./snippets -x '{"autoHost": false, "autoContentLength": false}'
