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

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.

SVR.JS documentation

You can read the SVR.JS documentation to get information on how to use SVR.JS.

npm scripts

• To build SVR.JS along with the zip archive, run npm run build.
• To check SVR.JS code for errors with ESLint, run npm run lint.
• To fix and beautify SVR.JS code with ESLint and Prettier, run npm run lint:fix.
• To run SVR.JS from the "dist" folder, run npm start.
• To test SVR.JS itself, run npm run dev. This removes existing configuration.
• To perform unit tests with Jest, run npm test.

File structure

The file structure for SVR.JS source code looks like this:

• assets - files to copy into dist folder and to the archive
• dist - contains SVR.JS, assets, and SVR.JS utiltiies
• generatedAssets - assets generated by the build script
• out - contains SVR.JS zip archive
• src - contains SVR.JS source code
  • index.js - entry point
  • handlers - handlers for servers
  • middleware - built-in middleware for servers
  • res - resources
  • utils - utility functions
• templates - EJS templates for build script to use
• tests - Jest unit tests
  • middleware - tests for middleware
  • utils - unit tests for utility functions
• utils - SVR.JS utilities (each utility has a single file)
• esbuild.config.js - the build script
• eslint.config.js - ESLint configuration
• jest.config.js - Jest configuration
• svrjs.json - SVR.JS version, name, documentation URL, and statistics server collection endpoint URL
