Cli tool for generating an express project. Instead of wasting extra time creating your project structure, start building right away

const chalk = require('chalk');
const ora = require('ora');

const creatingProjectSpinner = ora({
  spinner: 'star2'

const npmInstall = (projectName) => {
  npmInstallSpinner.start(chalk.cyan(`Installing required packages for ${projectName}`));

  const { spawn } = require('child_process');

  const installationProcess = spawn(`cd ${projectName} && npm install`, {
    shell: true
  });

  installationProcess.on('error', () => {
    npmInstallSpinner.fail(
      chalk.red(
        `
        An error occured, please try again. 
        If problem persist please raise an issue on Github`
      )
    );
  });

  installationProcess.on('close', () => {
    npmInstallSpinner.succeed(chalk.green(`Packages installed successfully`));

    console.log(
