minimist-lite's Issues

Release 2.2.0

@micalevisk whad do you think, is the current master ready to be released or is there anything else we can add? We could start creating version labels and add those to the individual tickets. I'll set up github projects page and we can add ideas there as well.

Automate publishing on NPM registry using GitHub Actions. And add CI workflow

Currently only you (I guess) can release new versions of this package.

We could use GitHub actions to automatically publish new versions to NPM registry after some event on this repo.

My proposal: publish on new releases on this repo.
An example of an workflow that publish the package on new Git Tags (that could be easily adapted):

You just need to add a secret called NPM_TOKEN with your NPM access token into this repo.

Also, to make thinks more safer, we can add another CI workflow that will be triggered on every PR that change some code. It will ran automated tests & coverage report. So we'll make sure that only good PRs are merged to the main branch.

To implement this, I need to know a bit more about how is the current workflow from changing the code til release a new version.

Proposal: Adding option for longer arguments names

So I thought if we'd be able to add support for longer names (currently it supports only "one letter" arguments). I have small issue because I'd like to add longer arguments. Like

const argvs = require("minimist")(process.argv.slice(2));


if ( || argvs.templateHelp) {

if (argvs.h || {

So when I call node index.js -th  this will call for templateHelp() function, not the help() one (because it divides arguments into argvs: { _: [], t: true, h: true })

Auto converting hex values to numbers

Original issue by @dimabru at

Hex parameters get auto-converted to numbers.
This results in a loss of information and change of values since hex values often exceed max int.

input args --a 0xffffffffffffffffffff

let args = minimist(process.argv.slice(2));

console output:

100000000000000000000 is clearly !== 0xffffffffffffffffffff

Seems parse error for this case

Original issue by @poppinlp at

I've run the code like node index.js -a="aaa=bbb" --a2="aaa=bbb"
And here are the output for process.argv, minimist parsed result and yargs-parser parsed result:

origin argv [
  'blabla not important',
minimist { _: [], a: 'aaa', a2: 'aaa=bbb' }
yargs parser { _: [], a: 'aaa=bbb', a2: 'aaa=bbb' }

You could see, for -a, minimist seems to get the wrong result.

BUG: function unknown called for non-options

Original issue by @johndeighan at

when I pass this to parseArgs() (using 'import parseArgs from 'minimist';' in an ES6 module'):

[ 'test/TopMenuShort.starbucks' ]

For example, my command line is node myscript.js test/TopMenuShort.starbucks, my "unknown" function is called, and this is output (though I've realized that this line is printed by my "unknown" function):

Unknown option: -test/TopMenuShort.starbucks

But the return value from parseArgs() is correct:

  _: [ 'test/TopMenuShort.starbucks' ],
  c: false,
  j: false,
  s: false,
  h: false,
  d: false

My work around is to simply return true from my "unknown" function, but that still has the problem that I can't just print the "unknown option" error message. I'm pretty sure that the function should only be called for unknown options, not for non-options on the command line.

New Feature : Allow for array in flag options

Would be really usefull if options could take a list of values
currently if I need to pass a list of value for a given option I have to repeat the flag :

bin -a fr -a be -a us
# will return { ..... a: ['fr', 'be', 'us'] }

What if we could parse :

bin -a fr,be,us
# and return { ..... a: ['fr', 'be', 'us'] }

of course there will be a debate on the separator, which should be an option.
This behavior could be trigger with the array option, if a separator option is provided.

just check this :

"a,z,e,r,t".split(undefined) // Array [ "a,z,e,r,t" ]
"a,z,e,r,t".split(',') // Array(5) [ "a", "z", "e", "r", "t" ]

Anybody interested in this ?

Add option to disable numeric conversion for arguments

Original issue by @whitlockjc at

const argv = require('minimist-lite')(process.argv.slice(2))

If I invoke my command using my-command 2.3, I end up with something like this:

{ _: [ 2.3 ] }

I realize if this was an option I could use opts.string to tell minimist to treat my option as a string but looks like there's no way to achieve the same for argument.

What I expect instead:

{ _: [ '2.3' ] }

TypeScript Definitions Not Included in Package

Hey all!

Thanks for forking minimist, it's nice to see work being done on an abandoned project once more. I pulled this project into my application and noticed TypeScript was complaining saying Could not find a declaration file for module 'minimist-lite'. I saw that you have an index.d.ts in the repo and looked in the package itself to investigate. To my surprise, I saw that the d.ts wasn't included with the packaged module (see the attached screenshot for details)

As a workaround I've created an empty minimist-lite.d.ts with the contents declare module 'minimist-lite';, but I know this isn't a sustainable route to take moving forward
