deno-bin
Use Deno via npm
You can use deno via npm or npx.
Note: This module installs deno at node_modules/deno-bin/bin/deno
, and you can use it via npx or npm's run-script.
Usage via npx
npx deno-bin
works like deno
executable. For example, you can run a deno script https://deno.land/std/examples/welcome.ts
like the below:
$ npx deno-bin run https://deno.land/std/examples/welcome.ts
Welcome to Deno!
You can also start repl:
$ npx deno-bin
Deno 1.1.0
exit using ctrl+d or close()
>
You can also use deno tools:
npx deno-bin fmt # Formats script
npx deno-bin lint --unstable # Checks lint rules
Usage via run-scripts
Use in scripts
in package.json.
First install deno-bin
:
npm i --save-dev deno-bin
(Note: This installs deno
executable at node_modules/deno-bin/bin/deno
internally.)
Then use deno
in your "scripts".
package.json:
{
...
"scripts": {
"foo": "deno run some-script.ts"
},
...
}
Then hit the command npm run foo
, and it executes deno run some-script.ts
with locally installed deno.
Ideas of usages
Use deno lint
in your node.js project
You can format your scripts with deno lint
which is faster than prettier. (deno lint
uses dprint internally, which is mostly compatible with prettier and is implemented in Rust.)
{
"scripts": {
"fmt": "deno fmt src"
}
}
Run some utility scripts
When you need some utility scripts in your repository, you can use deno for it. Because Deno can run typescript out of the box, you can skip any settings about typescript.
{
"scripts": {
"task": "deno run ./tools/some-task.ts"
}
}
About the version of deno
deno-bin
downloads the same version of deno
executable as its own version number. For example, if you install [email protected]
, you'll get deno v1.8.1
.
