Site | NPM Module | GitHub Repo
Node Powertools is an NPM module for backend and frontend developers that exposes powerful utilities and tools.
Install with npm:
npm install node-powertools
After installing via npm, simply require
the library and begin enjoying the powertools 🧰.
// In your functions/index.js file
const powertools = require('node-powertools');
Generate a random number between two numbers min
and max
. You can use options
to supply a sign or randomize the sign as well. If an array is supplied, a random element from the array is returned.
The default options.mode
is gaussian
but you can also supply uniform
.
powertools.random(0, 100, {mode: 'gaussian'}); // Output: 69
powertools.random(-100, 100, {mode: 'gaussian'}); // Output: -69
powertools.random(-100, 100, {mode: 'uniform'}); // Output: -69
powertools.random(['Apple', 'Orange', 'Pear']); // Output: Orange (random element)
Transform the input
into an array if it is not already.
powertools.arrayify(1); // Output: [1]
powertools.arrayify([1]); // Output: [1]
Asynchronously wait for the specified time
in milliseconds.
await powertools.wait(1000); // waits for 1000 ms (1 second)
Asynchronously wait for the specified fn
to return true
. You can use options
to supply a polling interval and timeout in milliseconds. The promise rejects if the timeout is reached.
// Call this function every 100 ms until it returns true or 30000 ms passes
await powertools.poll(function () {
return something === somethingElse;
}, {interval: 100, timeout: 30000});
Add the escape character \
before any character in str
that needs to be escaped for a RegExp
.
powertools.escape('*'); // Output: \*
powertools.escape('/'); // Output: \/
powertools.escape('\\'); // Output: \\
powertools.escape('.$^'); // Output: \.\$\^
Revive a str
into a RegExp
. Supports flags. Depending on how you want special characters to be treated, you can use powertools.escape(str)
prior to using powertools.regexify(str)
.
powertools.regexify('/Apple/'); // Output: RegExp /Apple/
powertools.regexify('/Apple/i'); // Output: RegExp /Apple/i
powertools.regexify('Apple'); // Output: Throws error (needs to start and end with /)
powertools.regexify('/Apple/x'); // Output: Throws error (x is not a valid flag)
powertools.regexify('/Ap.le/'); // Output: RegExp /Ap.le/
powertools.regexify(`/${powertools.escape('Ap.le')}/`); // Output: RegExp /Ap\.le/
Convert a date
to a timestamp in 3 formats: an ISO string
, a UNIX number
, or a plain-ol' JS Date
(as specified in options
).
The first argument date
can be a JS Date
, a UNIX timestamp number
, or a string
that will be parsed by the new Date()
method.
powertools.timestamp(new Date('2999/12/31'), {output: 'string'}); // Output: "2999-12-31T08:00:00.000Z"
powertools.timestamp(new Date('2999/12/31'), {output: 'unix'}); // Output: 32503622400
powertools.timestamp(new Date('2999/12/31'), {output: 'date'}); // Output: Tue Dec 31 2999 00:00:00 GMT-0800 (Pacific Standard Time)
powertools.timestamp(32503622400, {output: 'string'}); // Output: "2999-12-31T08:00:00.000Z"
powertools.timestamp(32503622400, {output: 'unix'}); // Output: 32503622400
powertools.timestamp(32503622400, {output: 'date'}); // Output: Tue Dec 31 2999 00:00:00 GMT-0800 (Pacific Standard Time)
Intelligently converts a value
to a type
how JavaScript should. The acceptable types are string
, number
, boolean
, array
.
powertools.force(undefined, 'string'); // Output: ''
powertools.force('true', 'boolean'); // Output: true
powertools.force('false', 'boolean'); // Output: false
powertools.force('0', 'boolean'); // Output: false
powertools.force('1,2,3', 'array'); // Output: ['1', '2', '3']
powertools.force('1,2,3', 'array', {force: 'number'}); // Output: [1, 2, 3]
