RingoJS

Ringo is a JavaScript platform built on the JVM and optimized for server-side applications. It's based on the Mozilla Rhino JavaScript engine.

It adds a number of features to Rhino that make it suitable for real-world, large-scale application development:

• A fast, auto-reloading, and CommonJS-compliant module loader.
• A rich set of modules covering I/O, logging, development tools and much more.
• Support for blocking and non-blocking I/O.
• Scalable HTTP server based on the Jetty project.
• Support for CommonJS packages to install or write additional software components.

Download and Installation

Download the latest precompiled release from the download page. Extract the archive and add the ringojs/bin directory to your local PATH for convinience.

If you use the Homebrew package manager on MacOS, you can use the ringojs formula: brew install ringojs

Take a look at the Getting Started Guide on Ringo's website for more details how to get started after you installed Ringo on your system.

Verify releases

To verify the integrity of a downloaded binary distribution, use the associated checksum file:

$ grep ringojs-x.y.z.tar.gz SHASUMS256-x.y.z.txt | sha256sum -c -

Verifying the integrity of provided checksums

Releases of RingoJS will be signed with one of the following GPG keys:

• 3.0.0 and newer: Philipp Naderer-Puiu <philipp@naderer-puiu.at>
  1405 9F17 6485 6429 089F B423 6167 CFBB BDF2 A508
• 2.0.0 and older: Philipp Naderer-Puiu <philipp@naderer-puiu.at>
  DE2A A9A1 B018 6C2F 622F D9EF 3F47 C28B 23EB 3072
• 1.2.0 and older: Philipp Naderer <philipp.naderer@gmail.com>
  8FF2 26B7 F268 547B 176F ABAC F312 313B 5CBC 0883

All official releases will be signed by at least one published key. Get the latest release key for 3.0.0 and newer with:

$ gpg --keyserver hkps://keys.openpgp.org --recv-keys 14059F1764856429089FB4236167CFBBBDF2A508

Download the checksums SHASUMS256.txt and separate signature SHASUMS256.txt.sig for the release, e.g.

$ curl -LO https://github.com/ringo/ringojs/releases/download/v4.0.0/SHASUMS256-4.0.0.txt
$ curl -LO https://github.com/ringo/ringojs/releases/download/v4.0.0/SHASUMS256-4.0.0.txt.sig

Now verify the checksums with:

$ gpg --verify SHASUMS256-4.0.0.txt.sig
gpg: assuming signed data in 'SHASUMS256-4.0.0.txt'
gpg: Signature made Wed Feb 23 12:07:10 2022 CET
gpg:                using RSA key 14059F1764856429089FB4236167CFBBBDF2A508
gpg: Good signature from "Philipp Naderer-Puiu <philipp@naderer-puiu.at>" [ultimate]

Building from Source

Ringo runs on top of the Java Platform. You can use an open implementation like Eclipse Temurin or Oracle's distribution. It uses Gradle as build tool.

If you have these installed, building Ringo is straightforward:

Check out Ringo using Git:

git clone git://github.com/ringo/ringojs.git

Change to the ringojs directory and run

./gradlew
