Libcurl bindings for Node.js. Based on the work from jiangmiao/node-curl.

Quick Start


npm i node-libcurl --save or yarn add node-libcurl

Simple Request

var Curl = require('node-libcurl').Curl;
var curl = new Curl();
curl.setOpt('URL', '');
curl.setOpt('FOLLOWLOCATION', true);
curl.on('end', function(statusCode, body, headers) {;'---');;'---'); 'TOTAL_TIME'));
curl.on('error', curl.close.bind(curl));

MultiPart Upload / HttpPost libcurl Option

var Curl = require('node-libcurl').Curl;
var curl = new Curl(),
    close = curl.close.bind(curl);
curl.setOpt(curl.option.URL, '');
curl.setOpt(curl.option.HTTPPOST, [
    { name: 'input-name', file: '/file/path', type: 'text/html' },
    { name: 'input-name2', contents: 'field-contents' }
curl.on('end', close);
curl.on('error', close);

Check the API Docs

Almost all CURL options are supported, if you pass one that is not, an error will be thrown.

Detailed Installation

The latest version of this package has prebuilt binaries (thanks to node-pre-gyp) available for the latest two (2) versions of Node.js on Active LTS (or Maintenance LTS, see and for the following platforms:

  • Linux 64 bits
  • Mac OS X 64 bits
  • Windows 32 and 64 bits

Just running npm install node-libcurl should install a prebuilt binary and no compilation will be needed.

If there is no prebuilt binary available that matches your system, or if the installation fails, then you will need an environment capable of compilling nodejs addons, which means python 2.7 installed and an updated C++ compiler able to compile C++11.

If you don't want to use a prebuilt binary you can pass --build-from-source to the arguments list.


The only compiler supported on linux is gcc >=4.8, also you need to have the libcurl development files available, if you are running debian for example, you must install the libcurl4-openssl-dev package.

If you don't want to use the libcurl version shipped with your system, since it's probably very old (debian 7 uses libcurl 7.26 which is more than 3 years old, and had more than 1000 bugfixes already), you can install libcurl from source, for the addon to use that libcurl version intead, you need to make sure that:

  1. curl-config tool is in the PATH,
  2. You have to setup LDFLAGS so that it poins to the correct directory where the curl lib files are:
export LDFLAGS="-Wl,-rpath,${LIBCURL_PREFIX}/lib";


You need to have installed OS X >=10.8 and xcode >=4.5


If installing using a prebuilt binary you only need to have the visual c++ 2015 runtime library. If building from source, you need to have Python 2.7 and Visual Studio >= 2015, you can get all that by running:

npm install --global --production windows-build-tools

Currently there is no support to use other libcurl version than the one provided by the curl-for-windows submodule.

nw.js (aka node-webkit)

From nw.js documentation:

Starting from 0.13.0, native modules built by node-gyp or npm in upstream can be supported.

In Linux and OSX you can just load the native module directly. In windows you’ll need to replace the file %APPDATA%\npm\node_modules\node-gyp\src\win_delay_load_hook.c with the one at Users/Advanced/Use Native Node Modules/

Since we require node-gyp as direct dependency, you probably will need to change that file directly in the node-gyp inside the node_modules folder of your project.

electron (aka atom-shell)

Currently there are no prebuilt binaries for electron, to install node-libcurl, do the following:

npm install node-libcurl --runtime=electron --target=1.0.2 --disturl= --arch=x64 --save

--target says you want to build for the electron version 0.34.1.

--arch says the module should be built for 64bit.

You can put those args in a .npmrc file, like so:

runtime = electron
target = 1.0.2
target_arch = x64
dist_url =


We are using yarn on this project.

If on Windows, run:

$ node tools/update-deps.js

Install the node modules:

$ yarn install

Build node-libcurl:

$ yarn pregyp rebuild
