The CanvasRenderingContext2D.stroke() method of the Canvas 2D API strokes the current or given path with the current stroke style using the non-zero winding rule.


void ctx.stroke();
void ctx.stroke(path);


A Path2D path to stroke.


Using the stroke method

This is just a simple code snippet which uses the stroke method to stroke a path.


<canvas id="canvas"></canvas>


var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');
ctx.rect(10, 10, 100, 100);

Edit the code below and see your changes update live in the canvas:

<textarea id="code" class="playable-code">
ctx.rect(10, 10, 100, 100);
var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
var textarea = document.getElementById("code");
var reset = document.getElementById("reset");
var edit = document.getElementById("edit");
var code = textarea.value;

function drawCanvas() {
  ctx.clearRect(0, 0, canvas.width, canvas.height);

reset.addEventListener("click", function() {
  textarea.value = code;
