It's a relatively simple NodeJS program that allows you to get the base64 encoded SHA-256 hash for a JS file or the code itself that you could later on use as the integrity of a script that you would integrate to a page so it won't be flagged by CSP or else.

Install

To install it you need to execute the following:

npm i hashmyjs

Note: Don't forget to use -g, --save, --save-dev if appropriate.

Usage

In NodeJS

const hmj = require('hashmyjs');

//Hashing from the STDIN (followed by a new line: `\RunKit, `\EOF`) or from file passed as arguments
hmj.run();

//Or if you want to hash code that is already present in your script:
let code = `...`;
let digest = hmj.hash(code);

In the CLI

hashmyjs -- [options] [files] #If used via an npm script

Help:

Usage: hashmyjs [options] [files...]

  A simple NodeJS JS file/code hasher.

  Options:

    -V, --version          output the version number
    -f, --format [format]  Specify the format of the output (text (default), json, csv) (default: text)
    -o, --output [path]    Output to a file instead of in the STDOUT (default: stdout)
    -i, --interactive      Forces to read the input from the STDIN
    -p, --prettify         Prettify the output
    -h, --help             output usage information

Nota bene

If you use wildcard * in the CLI to get files, NodeJS will have a hard time getting the file from the right URL so it will lead in errors.
