deno add
The deno add command adds dependencies to your project's configuration file.
It is an alias for
deno install [PACKAGES].
For more on how Deno handles dependencies, see
Modules and dependencies.
Examples Jump to heading
Add packages from JSR and npm:
deno add @std/path npm:express
By default, dependencies are added with a caret (^) version range. Use
--save-exact to pin to an exact version:
deno add --save-exact @std/path
This saves the dependency without the ^ prefix (e.g., 1.0.0 instead of
^1.0.0).
Treat unprefixed package names as npm packages:
deno add --npm express
Where dependencies are stored Jump to heading
If your project has a package.json, npm packages will be added to
dependencies in package.json. Otherwise, all packages are added to the
imports field in deno.json.
deno add [OPTIONS] [packages]...Add dependencies to your configuration file.
deno add jsr:@std/path
You can also add npm packages:
deno add npm:react
Or multiple dependencies at once:
deno add jsr:@std/path jsr:@std/assert npm:chalk
