The dev command in Extension.js is responsible for running your extension in development mode.
This command will start a new browser instance with your extension bundled and ready to run,
while also enabling live-reload as you modify the extension files during development.
Usage
You can run the dev command with the following syntax:
Description
The dev command is essential for a fast development workflow. It watches for changes in your extension's files,
recompiles them, and reloads the extension in real time. If you provide a URL, Extension.js will download and run the extension as if it were local.
It supports multiple browsers, and you can specify which one to use by passing the --browser flag.
Setting the browser to "all" will open the extension in all available browsers.
If a browser is not installed, the command will throw a compiler error.
Arguments and Flags
Below is a breakdown of the available flags for the dev command:
| Flag | Argument | What it does | Defaults to |
|---|---|---|---|
| [path or url] | The extension path or the remote extension URL | If a path is defined, it loads the local extension. If a URL is provided, it pulls the extension from a remote source and loads it as a local extension | process.cwd() |
| -b, --browser | The browser that will run the extension | Changes the browser (chrome, edge, all) |
"chrome" |
Best Practices
- Browser Specific Configurations: You can use the
--browserflag to run your extension in different browsers during the development process.
