ttlog (tagged template log)

Terminal and browser console colorizer

Ttlog console.log()s using tagged template syntax similar to chalk.js, but works in both the browser and terminal (Windows 10, unix/linux, and macOS). Ttlog also returns the plain-text string without colorization information so you can output it to a file or whatever.

Usage in node.js or webpack

const log = require('ttlog');
log`hello {white.bgBlack darkness} {underline my} {green old} {underline.blue.bgYellow friend}`;

Both outputting and writing a log in node.js

const fs = require('fs');
const log = require('ttlog');
fs.appendFile('mylog.log', log`{blue ${Date.now()}}: {green Bad things happened!!}`);

Usage in the browser

Put this in your html (head or body) if you host the file yourself:

<script src="ttlog.min.js"></script>

Use it like this in a .js or <script> tag:

log`hello {white.bgBlack darkness} {underline my} {green old} {underline.blue.bgYellow friend}`;

Todo

• Support console.info/warn/etc?
  • Problem is node doesn't support those, so it won't be consistent behavior
• Support import
  • import and require are competing and I haven't found a way to allow both from the same .js file
