Getting Started with Deno — What is Deno?

Running Your First Programs


In this section, you'll run some Deno programs to get used to how it's done. These files are located remotely. This is one cool feature of Deno, that you don't have to have the file on your local computer to run it.

Because Deno requires explicit permissions for many actions, like network access, file system access, and environment access, you need to use flags to allow your programs to use those features. The --allow-net flag gives you access to the network, --allow-read and --allow-write give read and write access, respectively, to the program, and --allow-env gives access to environment. You can see a full list of permissions on Deno's website.
