In this article, we will review a function named expandArgs(args) in Nue.js source code.
To give you some context, this function, expandArgs, is called in another function named getArgs. All these are part of cli.js file in Nue.js source code. Nue.js a web framework.
expandArgs
// [-npe] --> [-n, -p, -e]
export function expandArgs(args) {
const arr = []
args.forEach(arg => {
if (arg[0] == '-' && arg[1] != '-' && arg[2]) {
arg.slice(1).split('').forEach(el => arr.push('-' + el))
} else {
arr.push(arg)
}
})
return arr
}
You will find this above code in packages/nuekit/src/cli.js. The comment just above this function explains what this function does.
Given an argument -npe , it is converted to [-n, -p, -e] and the check is straight forward too.
if (arg[0] == '-' && arg[1] != '-' && arg[2]) {
and this function is used in getArgs function as shown below:
export function getArgs(argv) {
const commands = ['serve', 'build', 'init', 'create', 'docs']
const args = { paths: [], root: null }
let opt
expandArgs(argv).forEach((arg) => {
// skip
if (arg == '--') {
// test suite
} else if (arg.endsWith('.test.js')) {
args.test = true
