A fourth-generation implementation of Dataspaces and Syndicate for TypeScript and JavaScript, in both node.js and the browser. The implementation techniques herein are the subject of a forthcoming paper.


The main branch is where active development happens:

git clone -b main https://git.syndicate-lang.org/syndicate-lang/syndicate-js


This project uses yarn, not npm.

The repository is a monorepo, using yarn workspaces. Lerna is used as a thin veneer atop yarn workspaces, providing convenient automation for package version management and publication.

After a checkout, run:

make bootstrap

Alternatively, running:

yarn install
./node_modules/.bin/lerna exec yarn prepare

will download and install all dependencies and then build all the packages.


@syndicate-lang, an implementation of Syndicate for TypeScript and JavaScript.

Older versions

An earlier TypeScript+JavaScript implementation from early 2021 (the primary difference to main being a lack of object-capability support) can be found on the typescript1 branch:

git clone -b typescript1 https://git.syndicate-lang.org/syndicate-lang/syndicate-js

Finally, the babel-based branch is from 2018, and is an implementation for JavaScript only. It extends babel with new syntax and new plugins (rather than implementing its own error-tolerant parser, like typescript1 and main):

git clone -b babel-based https://git.syndicate-lang.org/syndicate-lang/syndicate-js
