Building SVR.JS

To build SVR.JS, you need Node.js 18.0.0 or newer.

Before building SVR.JS, install the npm packages using this command:

npm install

After installing the packages, build SVR.JS with this command:

npm run build

After running the command, you will get bundled SVR.JS script, around with built-in utilities and assets in the dist directory. You will also get a zip archive in out directory, that can be installed using SVR.JS installer. Additionally, you will get the SVR.JS Core package contents in the core directory, which you can publish by running npm publish in the core directory.

Installation (built from source)

To install SVR.JS you just built from the source code, you can install it via SVR.JS installer for GNU/Linux or manually.

If you want to install SVR.JS manually, you can read the server documentation.

If you want to install via SVR.JS installer for GNU/Linux, run this command:

curl -fsSL https://downloads.svrjs.org/installer/svr.js.installer.linux.20240509.sh > /tmp/installer.sh && sudo bash /tmp/installer.sh

You will be then prompted about the type of installation. Choose option “2” to install SVR.JS from the zip archive, and type in the path to the zip archive (hint: it is in the out directory).

After typing the path, you may be prompted to install dependencies via GNU/Linux distribution’s package manager. Proceed with the installation of dependencies.

After installation, SVR.JS should be listening at http://localhost.
