Node TypeError - "not a function" on require()'d class method

I have the following class:

const exec = require('child_process').execSync;

class Git {

    static branchExists (branchNameToCheck) {
        return ( exec(`git rev-parse --verify --quiet ${branchNameToCheck} > /dev/null`).length > 0 );
    }

}

module.export = Git;

This is called in the following (simplified) script:

#!/usr/bin/env node

const Git = require('./classes/Git');

if (Git.branchExists('develop')) console.log('success');

I get the following error:

Git.branchExists();
    ^

TypeError: Git.branchExists is not a function

Why is it not recognising branchExists as a function? When I run console.log(Git) I get {}.

I think it may just be a typo: module.export = Git; -> module.exports = Git;. If you don't define module.exports, the imported object ("Git" in this case) will be an empty object https://stackabuse.com/how-to-use-module-exports-in-node-js/
