  2. Navigate to the location of the code downloaded in your terminal
  3. Rename ".env.EXAMPLE" to ".env"
  4. Input your mySQL password in .env
  5. Run query found in db/schema.sql in your mySQL shell
  6. Run the following command in your terminal (make sure you're in the root directory of the application)
npm i && npm start
  1. Navigate to localhost:3001 in your browser

TECHNOLOGY

MySQL

Our server uses mySQL database to store users' confidential credentials, drawings, and comments. The following schema is used to show how each model references one another.

Canvas

Our drawing application is engineered with the Canvas API. Canvas provides a means for drawing graphics via JavaScript and the HTML canvas element. Our Javascript function can render objects such as shapes, lines, and strokes on the Canvas element at any given space coordinates, which in our application's case, the x and y coordinates of our cursor. You can learn more about Canvas by reading this documentation. The main drawing JavaScript functionality can be examined with the following code:

function start(e) {  // activate drawing by listening to a mouseclick 
  isDrawing = true;
  ctx.beginPath();
  ctx.moveTo(getX(e), getY(e)); // move to cursor's space coordinate
  e.preventDefault();
}

function draw(e) { // start drawing on your mouse's coordinate spaces
  if (isDrawing) {
    ctx.lineTo(getX(e), getY(e));
    ctx.strokeStyle = stroke_color;
    ctx.lineWidth = stroke_width;
    ctx.lineCap = "round";
    ctx.lineJoin = "round";
    ctx.stroke(); // render the path from moveTo and lineTo
  }
  e.preventDefault();
}

function stop(e) { // set drawing state to false when user let go of mouse hold
  if (isDrawing) {
    ctx.stroke();
    ctx.closePath();
    isDrawing = false;
  }
  e.preventDefault();
  restoreArray.push(ctx.getImageData(0, 0, canvas.width, canvas.height)); // push current imageData to our array for later restoration purposes
  startIndex += 1;
}

Tailwind CSS

Tailwind CSS makes it quicker to write and maintain the code of our application. By using this utility-first framework, we were able to provide a polished user interface for our customers:

Sequelize and Express

By using Sequelize ORM, we were able to consistently store data such as drawings and comments by updating queries, so our Express server can respond back to user's requests. Our social network service is entirely built on this stack to retrieve, store, and render data back to our client.
