41. Using the Canvas API
Anjana uses the Canvas API to create a graphic similar to the JavaScript logo. A yellow rectangle is drawn to the canvas element. Then, the fill color is changed to black, and the fillText method is used to draw text on the yellow background.

42. Accessing the Camera
Anjana begins building the selfie cam functionality. The existing application is refactored to use the getUserMedia API and add the video to a canvas element. The markup rendered by the main.js file is moved into the index.html file.

43. Refactoring the UI
Anjana refactors the UI of the selfie cam projects so the logos appear above the space where the camera image will show. The getVideo method is exported as a module and imported into the main.js file.

44. drawVideo Method
Anjana creates a drawVideo method that takes in a video and canvas element from the application. The method will draw the video image on the supplied canvas element. The drawVideo method is exported from the camera.js file so it can be imported and used in the application.

45. Using the Video Element
Anjana uses the exported functions from the camera.js module to display an image from the camera on the web page. The code is refactored, so the image will be displayed once the user clicks the button.

47. Building for Production
Anjana demonstrates how to build a production version of the application. Vite will provide errors when JavaScript features incompatible with the targeted browser runtime are used. An IIFE is used to enable support for top-level await.

49. ESLint
Anjana installs and configures ESLint to check the source code for syntax errors and other code problems. A "lint" script is added to the package.json file, and the lint script is also run any time the build script is run. The code in the selfie-cam repo linked below can be used as a starting point for this lesson.

53. Configuring GitHub Actions
Anjana looks at the configuration options for deploying a project using GitHub Pages. The finished selfie-cam repo is used as an example. Adding a YAML file to a repo's .github/workflows folder allows developers to configure custom GitHub actions for any automation tasks, including deploying a Vite project to GitHub pages. The code in the selfie-cam project linked below can be used as a starting point for this lesson.

54. Viewing GitHub Actions
Anjana looks at existing GitHub actions in the project and walks through each step displayed in the log. A successful action will have a green confirmation when it's completed. Failed actions are shown in red, and inspecting the logs helps developers understand why the action failed.

Anjana continues exploring the Meme Me application. The camera module has additional functionality using setInterval to continuously update the camera image, simulating a live camera feed. A Text module has been added to draw the meme text on a separate canvas, making it more flexible when the text is updated.
