Hacky script to turn JSON into a .env file and spit out corresponding JS object to clipboard (mac only for now)

envify.js

'use strict';
const path = require('path');
const fs = require('fs');

const argv = process.argv.slice(2);
let [filename, prefix = ''] = argv;

if (prefix) {
    prefix = `${prefix}_`;
}

const jsonPath = path.resolve(__dirname, filename);
const outputPath = '.env_generated';

const envObj = require(jsonPath);

let envString = '{';

const envGetter = envKey => `process.env["${envKey}"]`;

const envFile = Object.keys(envObj).map(k => {

    const envKey = `${prefix}${k.toUpperCase()}`;

    envString += `\n\t"${k}": ${envGetter(envKey)},`;

    const envVal = envObj[k];
    const envValue = `"${envVal.replace(/\r?\n/g, '\\n')}"`;

    return `${envKey}=${envValue}`;
}).join('\n');

envString += '\n}';

fs.writeFileSync(outputPath, envFile);

const cp = require('child_process');
const clip = cp.exec('pbcopy', (_err, _stdout, _stderr) => {/* optionally do something */});
clip.stdin.write(envString);
clip.stdin.end(() => process.stdout.write(`\rCopied ${envString.length} characters.\n`));
