A very simple module called argv that allows you to:
- Check whether certain flags exist in
process.argv - Get the value of a flag in
process.argv
# With npm npm install @lando/argv # With yarn yarn add @lando/argvThis module has two functions hasOption and getOption.
Checks to see if a flag exists in process.argv.
const argv = require('argv'); // Will return Boolean const hasDebug = argv.hasOption('--debug'));Returns the value of the flag. If the flag is a switch then it will return true|false by default. If the flag has a string value it will return that string value.
// File: myscript.js const argv = require('argv'); console.log(argv.getOption('--debug'));The above code will produce the following:
node myscript.js --debug > true node myscript.js --debug "trill" > trill hyperdrive list --debug=trill > trillYou also can replace the default Boolean value with the defaultValue option.
// File: myscript.js const argv = require('argv'); console.log(argv.getOption('--debug', {defaultValue: 'the-truth-is-out-there'}));node myscript.js --debug > the-truth-is-out-thereIf you have a question or would like some community support we recommend you join us on Slack. Note that this is the Slack community for Lando but we are more than happy to help with this module as well!
If you'd like to report a bug or submit a feature request then please use the issue queue in this repo.
We try to log all changes big and small in both THE CHANGELOG and the release notes.
git clone https://github.com/lando/argv.git && cd argv yarn installIf you dont' want to install Node 14 or Yarn for whatever reason you can install Lando and use that:
git clone https://github.com/lando/argv.git && cd argv # Install deps and get node lando start # Run commands lando node lando yarn# Lint the code yarn lint # Run unit tests yarn testTo deploy and publish a new version of the package to the npm registry you need only create a release on GitHub with a semver tag.
Note that prereleases will get pushed to the edge tag on the npm registry.
