mod

Warning This Deno module is deprecated. I recommend using deno init instead.

mod is a command line tool to quickly scaffold a new Deno module. It creates app and dependency entrypoints, a .gitignore file and has options to add a test-driven setup and/or include a basic CI pipeline.

Try it without any installation:

deno run \
--allow-read \
--allow-run=git \
--allow-write=my_deno_module \
https://deno.land/x/mod/mod.ts \
--name my_deno_module

deno run `
--allow-read `
--allow-run=git `
--allow-write=my_deno_module `
https://deno.land/x/mod/mod.ts `
--name my_deno_module

Installation

mod requires deno and optionally git. You can get the latest stable release from deno.land/x:

deno install --allow-read --allow-run=git --allow-write -fn mod https://deno.land/x/mod@v2.3.9/mod.ts

You can also get the unstable canary release from GitHub by installing via the main branch’s raw URL:

deno install --allow-read --allow-run=git --allow-write -fn mod https://raw.githubusercontent.com/GJZwiers/mod/main/mod.ts

Permissions

mod requires the following permissions:

• read: to check if files already exists before writing.
• run=git: to run git commands, more specifically git init
• write: to make files as part of the module initialization.

Omitting run permissions is possible, but it means a Git repository will not be initialized automatically.

Usage

mod

This will create the following file structure in the current working directory:

.
├── .gitignore
├── deps.ts
├── dev_deps.ts
├── mod.ts

Note that mod does not overwrite files unless --force is used explicitly. This means the program can also be used to ‘fill in the blanks’ in a directory where not all of the files above are present yet.

Also note that mod does not perform editor-specific setups such as enabling Deno in VS Code via .vscode/settings.json.

If git is installed on the machine then git init will be run as well.

To create the new module in a new directory:

mod --name my_deno_module

This will create the following file and directory structure:

.
├── my_deno_module
|   ├── .gitignore
|   ├── deps.ts
|   ├── dev_deps.ts
|   ├── mod.ts

mod can also create other files in addition to the basics, such as a workflow file for GitHub Actions:

mod -n my_deno_module --ci

.
├── my_deno_module
|   ├── .github
|   |   ├── workflows
|   |   |   ├── build.yaml
|   ├── .gitignore
|   ├── deps.ts
|   ├── dev_deps.ts
|   ├── mod.ts

You can also initialize with JavaScript:

mod --js

.
├── .gitignore
├── deps.js
├── dev_deps.js
├── mod.js

Options

mod can create other files with the module, such as an import map or a Deno configuration file. To see what options and flags are available use:

• mod --help if you have the CLI installed or
• deno run https://deno.land/x/mod/mod.ts --help
