Dependency-free, opinionated node.js CLI skeleton generator that is structured to allow automatic rolling upgrades of framework code.
Opinionated choices:
- CLI framework:
commander
- Logging:

- Tests:
jest
- Promise flow control:
async
- Console colors:
chalk
All packages are installed at the latest release on new project creation using npm install
.
Install
Install the global cli-gen
executable:
npm install -g cli-gen
Or use without installing by using npx
(not npm
):
npx cli-gen
Usage
Initial use: in a blank directory, run
cli-gen --apply
to create a new CLI project skeleton. The project name is used to generate a newpackage.json
file. Follow the development guidelines below to ensure that any skeleton code can be automatically updated in future releases.Upgrade boilerplate: run
cli-gen --apply
in an existing project directory. This requires that the development guidelines below are adhered to.Dry run: run
cli-gen
without arguments to see whatcli-gen
would have done.Link command globally:
npm link .
Development Guidelines
A single CLI command corressponding to your project name will be specfied in package.json
under the bin
entry. This command will perform git
-style subcommands using the commander
module, while setting up the CLI environment (logging, global helpers, etc.).
CLI subcommands follow a directory-based structure in the following root folder: lib/cli/verbs
. A bare-bones "about" verb is created in the about
folder.
Following the development guidelines below, user code and framework/skeleton code will be isolated for independent upgrades.
Guideline 1
- Interface with the framework as independent
commander
subcommands.
New features should start with a subcommand folder in lib/cli/verbs
with its specified set of options.
Guideline 2
- Additive source changes are fine.
Files and directories can be added anywhere, as long as files do not include the following text on its own line:
/* cli-gen: auto-generated, do not edit. */
