Is there a way to give read permissions for a subdirectory in Deno?

Question

I have a script that accesses files in a sub-directory. It works when you allow all read access, but all of my attempts at giving read access only to that directory have failed. Is there a way to specify directories via relative paths for --allow-read?

Answer 1

The command

deno run --allow-read=./resources  .\testread.ts

gives you read access only to the subdirectory ./resources

so this works:

const text1 = Deno.readTextFile("./resources/test.txt");

and this throws an exception:

const text1 = Deno.readTextFile("./test.txt");

PermissionDenied: read access to "./test.txt", run again with the --allow-read flag

You can also specify more than one directory in a comma separated list:

deno run --allow-read=./resources,./other  .\testread.ts

If you need write access, it works the same way as for read access:

deno run --allow-write=./resources,./other  .\testread.ts
