Nexe Builds

Current version 0.3.1. Current remote URL: https://github.com/yoavain/nexe-builds/releases/download/0.3.1/

[Nexe] is a fantastic tool for turning Node.js applications into single binaries. This repository provides automation to pre-build and distribute the node binaries, so you don't have to!

How to Use

To use the pre-built binaries with nexe just add --remote https://github.com/yoavain/nexe-builds/releases/download/0.3.1/

Script example:

# Install Nexe
npm install nexe
# Save remote URL as variable
NEXE_REMOTE="https://github.com/yoavain/nexe-builds/releases/download/0.3.1/"
# Do nexe build
npx nexe ./myScript.js --remote "$NEXE_REMOTE"

Security Disclaimer

This repository utilizes Nexe's standard built process and is run via Github Actions. If you wish to have a secure build of Node.js for Nexe then please build it from scratch yourself. All code and artifacts from this repository are provided as is with no warranty or guarantees.

Understanding releases

We use our release version to mark changes in how we build the binaries, such as the version of Nexe used. Please refer to RELEASE_LOG.md for more details.

Adding to the Build Matrix

If you want other builds to be created and published, please open a Issue ticket 👍

Motivation

Urban Dynamics makes use of Nexe for a number of projects we do. It's a great tool but the pre-built binaries are becoming a bit stale compared to the Node.js release schedule. So, we decided to open source our build automation which was creating and publishing prebuilt binaries. Enjoy 🚀

Build Call Flow

1. bin/run_cd: Gets the prior git commit, calls bin/check_assets, and then calls bin/install_dependencies plus bin/build_nexe if a build is needed.
