Install

jint ships as one binary per platform. It carries its own runtime, so you need no JavaScript runtime to run it or to write .ts rules.

Install script

curl -fsSL https://raw.githubusercontent.com/sedulustech/jint/feat/decisions-model/install.sh | bash

The script picks the binary for your platform, checks its sha256 against checksums.txt, and installs it to ~/.local/bin/jint. If that directory is not on your PATH, the script says so.

To install a specific release, set VERSION on the bash side of the pipe:

curl -fsSL https://raw.githubusercontent.com/sedulustech/jint/feat/decisions-model/install.sh | VERSION=v1.2.3 bash

npm

npm install -g @sedulus/jint@rc   # or add it as a devDependency
npx @sedulus/jint@rc --version

Download a binary

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

Download the archive for your platform from the site’s download page or from the GitHub releases. Check it, 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

jint.sh mirrors the releases under /dl/, in the same layout GitHub uses (/dl/latest/download/<archive> and /dl/download/<tag>/<archive>). To make the install script read from the mirror, set RELEASE_BASE=https://jint.sh/dl.

Beta

The beta channel is one unversioned build, overwritten on every push to the beta branch. It is not a GitHub release and has no tag. Install it through the mirror:

curl -fsSL https://raw.githubusercontent.com/sedulustech/jint/feat/decisions-model/install.sh | RELEASE_BASE=https://jint.sh/dl VERSION=beta bash

Or download an archive from https://jint.sh/dl/download/beta/<archive>, with its checksums.txt beside it. https://jint.sh/dl/download/beta/COMMIT names the commit the beta was built from. Because the beta is overwritten, pin a tagged release when you need the same binary twice.

Requirements

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

First run

jint asks a classifier endpoint its questions, so it needs an API key in the environment: JINT_API_KEY, or OPENAI_API_KEY. It runs only the rules a config names, so write a jint.config.ts first; running jint run without one prints every rule domain and a working example. See Configuration for the config and Rules for the rules.

Uninstall

Delete the binary: rm ~/.local/bin/jint.
