A Nodejs lib that arranges the arguments passed to a function based on pattern string
This library intends to help the developers to maintain backwards compatibility in their functions, by making and maintaining optional parameters, and not worrying to write code to assign the correct values to the arguments
npm install parse-args -S
// params ([name], [email], age, [gender])
function testFn(name="vin", email="diesel@mail.com", age, gender="female"){
if(!email) {
age = name;
name = "vin"
} else if (!age) {
age = email
email = "diesel@mail.com"
}
}
testFn("john", 34)
var parseArgs = require("args-pattern")
function testFn() {
let [name, email, age, gender] = parseArgs(arguments, "[name] [, email] , age [, gender]", {
args: ['vin', 'diesel@mail.com', 34, "female"]
})
// Output name === "john"
// Output email === "diesel@mail.com"
// Output age === 35
// Output gender === "female"
}
testFn("john", 35)
Even though the real world examples can get a little more complicate, parse-args
library
will be there to rescue, so that you can avoid a lot of spaghetti code 👍
