How To Avoid Permission Issues When Using Denon

I was running denon, which is like nodemon in node, but I'm getting permission issues even when I've manually specified the relevant flags (specifically --allow-net flag.) How do I

Solution 1:

Without knowing the exact error it's hard to give you the correct answer, but denon is unstable, it has several issues.

One of those errors that you might be affecting you is if you're trying to watch a folder that you may not have ownership you'll get:

error: Uncaught PermissionDenied: Permission denied (oserror13)

for example, if I run denon on /tmp I get that error thrown, even if the folder has all permissions.

Even though nodemon works perfectly on /tmp.

My recommendation is to use nodemon until denon is stable or until there's a better tool for deno.

You can do so by using --exec flag

nodemon --exec deno run --allow-net index.ts

For convenience you can use nodemon.json with the following content:

{"execMap":{"js":"deno run --allow-net","ts":"deno run --allow-net"},"ext":"js,json,ts"}

And now just use: nodemon index.ts

Solution 2:

You can create a denon.json file in your project root.

{"scripts":{"start":"deno run --allow-env --allow-net server.ts"}}

Then you can run the script this way (assuming denon installed):

denon start

https://deno.land/x/denon

Hope it helps!

Solution 3:

adding --allow-net solved it for me.

for some reason creating the denon.json file manually didn't work, so I had to run deno --init and add --allow-net to the start cmd

"start":{"cmd":"deno run --allow-net app.ts","desc":"run my app.ts file"}
