Live Reload

Live Reload is a server watcher, written in Deno, for TypeScript and JavaScript that will reload the server when it detects a change in any TypeScript or JavaScript file.

Usage

To use Live Reload, first have Deno installed, and then use a terminal and write:

deno run --allow-read --allow-run https://deno.land/x/live_reload@0.0.3/reload.ts --main=main.ts

Note that the argument for –main should be the main module for the server. Also the main module can also be a .js file too.

The –allow-read and –allow-run are needed because the program needs to access files and start subprocesses.

To restrict permissions, add command line arguments such as allow-net and allow-read. For example, to restrict the Deno subprocess to only read and net access use:

deno run --allow-read --allow-run https://deno.land/x/live_reload@0.0.3/reload.ts --main=main.ts allow-net allow-read

The list of permission arguments are available here.

Note that arguments for permissions leave off the ‘–’ at the beginning of the permission and having no permisions is interpretted as having all permissions (-A).

To give no permissions use:

deno run --allow-read --allow-run https://deno.land/x/live_reload@0.0.3/reload.ts --main=main.ts allow-none
