I am trying to use yargs to validate arguments sent in a POST request. I use
yargs.config(req.body).argv to read the input and make sure all the required fields are there, before I perform my BI.I might be missing something basic and fundamental, but the 2nd POST request I get only adds anotehr 'layer' of parameters, instead of replacing it. I tried calling
yargs.reset(), but it doesn't seem to do what I expected it would.Is there some other way to use yargs for my purpose? or maybe it's not a good use case for the library?
cross-spawn
my_script input input2 input3 --other option
$0 [input..] does the trick
remote with two sub-commans - add and rm. Each of these sub-commands will require one or more values. I'm struggling to achieve that. The closes I found was "positionals", but I can't figure out how to say that there should be at least one "positional" specified and how to say for which positional the number of required values. How is this supposed to be done with yargs? Here is what I have so far:
const yargs = require('yargs');
yargs.command(
'remote',
'Manage a remote,
(yargs) => {
yargs.positional('add', {
describe: 'Adds a remote',
type: 'string'
});
yargs.positional('rm', {
describe: 'Remove a remote',
type: 'string'
})
}).argvadd and rm subcommands should expect some number of arguments?
add or rm should be specified?
required: true probably
add or rm
.demandCommand
git remote rename <old> <new>
git remote remove <name>
Hi guys,
I have a problem no other command line parsing library I've explored (probably) supports and since the generality of yargs, maybe you have some solution for it, but I can't really tell as from many options you provide, I'm a bit lost :).
I want to get a list of possibly multiple commands with arguments in a row as defined on the command line, so that I can build from it a "functional pipeline", that will be applied to some array/iterator/stream.
Is this case somehow solvable with yargs?
Many thanks...
Had a quick question. I am building a CLI using yargs and want to give users the options to add their own commands in a specific folder. I know I can use the following to accomplish this:
.commandDir(path.join(process.cwd(), 'commands))This works great when the folder exists in the project, but if it does exist I get the following error:
Error: Error: ENOENT: no such file or directory, scandir 'DIRECTORY_PATH'is there a way add the command directory ONLY if the directory exists?
thanks.
yargs supports command lines as the following: myprog -r repo -v clone -p proj -a, i.e. having arguments (-r, -v) that are available for each command and are specified before it and arguments that are only valid for a specific command (-p, -a). Similar to https://git-scm.com/docs/git. I tried using something like yargs.option(...).command(...) but that did not seem to work.
