CurlGenerator

CurlGenerator is a small (~1kb), dependecy free, library to generate curl snippets. Currently it has only 1 API, but I'm open to suggestion on how to improve and to integrate with different http request libraries.

Getting started

install in your project

npm install curl-generator

Or you can download the file you need from the dist folder

Using it

import {CurlGenerator} from "curl-generator";

const curlSnippet = CurlGenerator({url: "https://jsonplaceholder.typicode.com/posts/1"}); 
// curlSnippet => curl "https://jsonplaceholder.typicode.com/posts/101"

If you are going to import it with in node via require

const CurlGenerator = require("curl-generator").CurlGenerator;

API

Currently the library export just CurlGenerator, and it's a function with just 1 object parameter with the following description:

/**
 * @param {string} url - the request url
 * @param {string} [param.method] - a value between ("GET" | "POST" | "PUT" | "PATCH" | "DELETE" | "HEAD" | "OPTIONS" | "CONNECT" | "TRACE" | "QUERY") it's case insensitive
 * @param {Object<string, string>} [param.headers] - an object containing the headers of the request
 * @param {Object} [body] - the body of the request
 */

Note: The QUERY method is not yet an official HTTP standard but is based on an IETF draft proposal.

Example of a more "advanced" use

import {CurlGenerator} from "curl-generator";

const params = {
    url: "https://jsonplaceholder.typicode.com/posts",
    method: "POST",
    headers: {
        "Content-type": "application/json; charset=UTF-8"
    },
    body: {
        "id": "123-456-789",
        "key1": "value 1",
        "key2": `a "complex" value`
    }
}
const curlSnippet = CurlGenerator(params); 
// curlSnippet => curl "https://jsonplaceholder.typicode.com/posts" -X POST -H "Content-type: application/json; charset=UTF-8" -d "{\"id\":\"123-456-789\",\"key1\":\"value 1\",\"key2\":\"a \\\"complex\\\" value\"}"

You can also pass Curl options as additional options:

import {CurlGenerator} from "curl-generator";

const params = {
    url: "https://jsonplaceholder.typicode.com/posts/1"
}
const options = {
    output: "test.txt",
    silent: true
}
const curlSnippet = CurlGenerator(params, options); 
// curl "https://jsonplaceholder.typicode.com/posts/1" --output test.txt --silent

Currently the following options are supported (you can submit a PR if you need others):

Name	Type
compressed	boolean
compressedSsh	boolean
fail	boolean
failEarly	boolean
head	boolean
include	boolean
insecure	boolean
ipv4	boolean
ipv6	boolean
listOnly	boolean
location	boolean
locationTrusted	boolean
noKeepalive	boolean
output	string
showError	boolean
silent	boolean
ssl	boolean
sslv2	boolean
sslv3	boolean
verbose	boolean

Contributing

The library is written in typescript (it's my first typescript project so I'm very open to tips and suggestions) and it comes with 3 scripts Dev build with watch

npm run dev

Build bundle

npm run build

Test (I plan to move testing with jest if the library grows)

npm run test

The build generate three files:

• dist/curl-generator.cjs.js A CommonJS bundle, suitable for use in Node.js, that requires the external dependency. This corresponds to the "main" field in package.json
• dist/curl-generator.esm.js an ES module bundle, suitable for use in other people's libraries and applications, that imports the external dependency. This corresponds to the "module" field in package.json
• dist/curl-generator.umd.js a UMD build, suitable for use in any environment (including the browser, as a <script> tag), that includes the external dependency. This corresponds to the "browser" field in package.json
