Open-Source collaborative IDE with many features and extremely quick setup!

Currently work-in-progress/early alpha, but you can try it out with npx devsession in the directory in which you want to start a coding session, or by downloading the GUI starter from the latest release.

More details are available on the devsession website: https://lukasbach.github.io/devsession/

CLI

You can run devsession from anywhere by entering npx devsession, which will automatically download, install and run devsession. You can install it globally by entering npm i -g devsession, so you can just invoke devsession at any time.

You can also install devsession as a dev dependency to your project and create an npm script in your package.json with preset CLI arguments to quickly enter a session that fits the projects needs.

You can use the following arguments:

• -p, --port [port], The port on which to run the server. Defaults to 8020.
• -k, --adminkey [key], This key can be used to register a user as an admin. Defaults to a random string.
• -d, --dir [dir], The project directory. Defaults to the current directory.
• -v, --verbose, Log all socket messages for debugging.
• -a, --autosave, Duration (in seconds) of periodic auto saving of all open files. 0 = disabled. Defaults to 120.

Building/Contributing

The project is set up as a monorepo using Lerna. Note that, prior to doing anything else and especially prior to installing dependencies, you need to run npx lerna link to establish symlinks between the packages.

• To start developing, run yarn && yarn start in the root directory. This will start a development server for the backend and the frontend and automatically recompile if changes are detected. The backend starts on port 8020, the frontend on port 3000. To debug, open the frontend from the url: http://localhost:3000/?adminkey=adminkey&backend=http://localhost:8020

• To run a new build, run yarn && yarn build. This will build the common package, the backend, the frontend, the website and the guistarter app.

• To release a new version, run yarn && yarn pub. This will build everything, bump versions for all packages, upload new versions for the packages which are deployed on npm and commit and push the version bumps. The CI pipeline will pick that up and redeploy the website and attach the guistarter binaries with the github release.
