Starting a new project
Starting a new project with Deno has always been incredibly simple: you just need a single file to get going. No need for any configuration files, dependency manifests, or build scripts.
Users coming from other ecosystems are often not used to this simplicity - they
often look for a tool to scaffold out a basic project structure to get them
started on the right path.
deno init subcommand scaffolds a basic Deno
$ deno init ✅ Project initialized Run these commands to get started deno run main.ts deno test $ deno run main.ts Add 2 + 3 = 5 $ deno test Check file:///dev/main_test.ts running 1 test from main_test.ts addTest ... ok (6ms) ok | 1 passed | 0 failed (29ms)
This subcommand will create two files (
files provide a basic example of how to write a Deno program and how to write
tests for it. The
main.ts file exports a
add function that adds two numbers
together and the
main_test.ts file contains a test for this function.
You can also specify an argument to
deno init to initialize a project in a
$ deno init my_deno_project ✅ Project initialized Run these commands to get started cd my_deno_project deno run main.ts deno test
