deno

如果项目使用Deno，可使用此技能。通过此技能初始化并操作Deno项目，添加或移除依赖项（JSR与npm），以适当权限运行任务与脚本，并充分利用内置工具（fmt/lint/test）。

name: deno
description: If the project uses deno, use this skill. Use this skill to initialize and work with Deno projects, add/remove dependencies (JSR and npm), run tasks and scripts with appropriate permissions, and use built-in tooling (fmt/lint/test).
triggers:
- deno
- deno.json
- deno.jsonc
- deno.lock

Deno

Use Deno as the default runtime/tooling when the repo contains deno.json/deno.jsonc, uses deno.lock, or scripts/documentation reference deno task, deno run, deno test, etc.

Quick decision rules

  • •Prefer deno task <name> if the repo defines tasks.
  • •Use deno add / deno remove to manage dependencies (writes to config).
  • •Be explicit about permissions for deno run / deno test.

Common operations

Initialize a new project

bash
deno init

Add dependencies (JSR and npm)

bash
# JSR (recommended for Deno-first packages)
deno add jsr:@std/path

# npm packages are supported too
deno add npm:react

# multiple at once
deno add jsr:@std/assert npm:chalk

Remove dependencies

bash
deno remove jsr:@std/path

Run a script

bash
# Minimal permissions: only what the program needs
# Examples:
#   --allow-net=api.example.com
#   --allow-read=./data
#   --allow-env=FOO,BAR

deno run --allow-net --allow-read main.ts

Run tasks

bash
# list tasks
deno task

# run a task defined in deno.json/deno.jsonc
deno task dev

Formatting, linting, testing

bash
deno fmt
deno lint
deno test

# common permissioned test run
deno test --allow-net --allow-read

Install / run CLIs

bash
# Run a JSR or npm package's CLI without installing globally
deno x jsr:@std/http/file-server -p 8080

# Install globally (requires choosing permissions at install time)
# Prefer the smallest set of permissions; avoid blanket flags unless necessary.
deno install -g -N -R jsr:@std/http/file-server -- -p 8080

Notes / pitfalls

  • •Deno is secure-by-default: missing permissions cause runtime errors; add the smallest set of --allow-* flags needed.
  • •Dependency specifiers:
    • •jsr: for JSR registry packages
    • •npm: for npm packages
    • •URL imports are also supported (and cached)
  • •Lockfile: deno.lock helps ensure reproducible dependency resolution.
