Draw text in Node.js

render.js

'use strict';

const fs = require('fs');
const Canvas = require('canvas');

const width = 600;
const height = 300;
const canvas = new Canvas(width, height); // creates 400px * 200px size canvas

// draw
const ctx = canvas.getContext('2d'); // get context to draw

// fill whole background
ctx.fillStyle = "#fff";
ctx.fillRect(0, 0, width, height);

// draw text
ctx.font = '48px italic "Apple SD Gothic Neo"'; // sets font size/style
ctx.fillStyle = '#333'; // sets font color
ctx.rotate(0.3); // rotates text, please note that rotate is not required for drawing text. this is just for demo purpose :)
ctx.fillText('태사기님 안녕하세요!', 40, 60); // draws text at point (40px - X axis, 60px - Y axis)

// save image
fs.writeFile('text.png', canvas.toBuffer(), (e) => {
  if (e) { 
    // handle error at here
    console.error('oops, something went wrong!', e.stack);
    return;
  }

  console.log('done!');
