Running locally
The next step after scaffolding out a new project, is to actually start it. To
do this you can just deno task start.
$ deno task start
Watcher Process started.
Server listening on http://localhost:8000If you want to start manually without Deno task, deno run the main.ts with
the appropriate flags. You will need to provide permission flags for:
--allow-net: This is required to start the HTTP server.--allow-read: This is required to read (static) files from disk.--allow-env: This is required to read environment variables that can be used to configure your project.--allow-run: This is required to shell out todenoandesbuildunder the hood during development to do type stripping. In production this is done using a WebAssembly binary.
For development, you also want to run with the --watch flag, so the fresh
server will automatically reload whenever you make a change to your code. By
default --watch only watches over files in your module graph. Some project
files like static files are not part of the module graph, but you probably want
to restart/reload whenever you make a change to them too. This can be done by
passing the extra folder as an argument: --watch=static/.
Finally you might want to add a --no-check flag to disable the type checking
during development. Typically many people already get type checking from their
editor through the use of the Deno language server, so this is a good way to
speed up the inner loop iteration time. During CI you probably want to run with
--no-check=remote disable type checking of remote dependencies (because these
are out of your control).
Combining all of this we get the following deno run command:
$ deno run --allow-net --allow-read --allow-env --allow-run --watch=static/ --no-check main.ts
Watcher Process started.
Server listening on http://localhost:8000If you now visit http://localhost:8000, you can see the running project. Try
change some of the text in routes/index.tsx and see how the page updates
automatically when you save the file.
