Install

jint is in beta. Download it from the download page. That is the only way to install it for now.

Download a binary

Each release carries one archive per platform and a checksums.txt that covers all of them:

Platform	Archive
Linux x64	`jint-linux-x64.tar.gz`
Linux arm64	`jint-linux-arm64.tar.gz`
macOS Apple silicon	`jint-darwin-arm64.tar.gz`
macOS Intel	`jint-darwin-x64.tar.gz`

Check the archive, unpack it, and put the jint binary on your PATH:

sha256sum -c --ignore-missing checksums.txt   # on macOS: shasum -a 256 -c --ignore-missing checksums.txt
tar -xzf jint-linux-x64.tar.gz
install -m 755 jint ~/.local/bin/jint

Requirements

jint carries its own runtime, so you need no JavaScript runtime to run it or to write .ts rules.

jint asks a classifier endpoint its questions, so it needs an API key in the environment: JINT_API_KEY, or OPENAI_API_KEY.

On Linux the only system requirement is glibc. On musl-based images such as Alpine, install a glibc layer first or use a glibc base image.
