How to Run a Script with All Permissions Using Deno

Deno, Permissions1 min read

If you're using Deno to run scripts, you may encounter situations where your script needs to access resources that require certain permissions. For example, if your script needs to read or write files, it needs the read and write permissions. By default, Deno only grants scripts the permissions they need to run, so you'll need to explicitly grant your script additional permissions if it requires them.

To run a script with all permissions, you can use the --allow-all flag when executing the script. This flag grants the script permission to access all resources on the system. Here's an example:

1deno run --allow-all app.ts

In this example, app.ts is the name of your script file. Replace it with the actual name of your script file.

Alternatively, you can grant individual permissions to your script by using flags like --allow-read, --allow-write, --allow-net, etc. For example:

1deno run --allow-read --allow-write app.ts

This command grants the read and write permissions to your script.

It's important to note that granting all permissions to a script can be dangerous, especially if you're running a script from an untrusted source. Always make sure you trust the script before granting it full access to your system.

In summary, running a script with all permissions in Deno is easy – just use the --allow-all flag. However, be cautious when running scripts with full permissions and ensure you trust the source of the script.
