Deno Deps Detective

detective (noun)

a person, especially a police officer, whose occupation is to investigate and solve crimes.

Don’t let your deno project dependencies become a crime scene!

detective helps you keep track of your deno dependencies and their versions. It also helps you track important metrics like number of files and total size. It’s like a detective for your deno project dependencies. (Last sentence generated by an AI. Brilliant. 😅)

Installation

deno install --allow-read --allow-write --allow-net --allow-env --allow-run --unstable https://deno.land/x/detective/detective.ts

Usage

First, create a deps.json file using deno info --json <your_root.ts>.

deno info --json ./src/index.ts > deps.json

Then, run detective with the deps.json file as an argument.

detective deps.json

The default mode will show you diagnostics of your dependencies.

You can also use --json to output a JSON version of the diagnostics.

detective --json deps.json

Example

$ deno info --json ./src/index.ts > deps.json
$ detective deps.json
