This API globally at the edge, to minimize latency for your API's consumers. Once it's live,īuilding an image resizing API with Deno and ImageMagick is not only simple andįast, but can be done within 100 lines of code. Once you've connected, it should take up to a minute to deploy. Finally, your entrypoint should be main.ts. "GitHub Automatic", which will deploy every time there's a merge onto your For example, if you have a pixel with red 255, green 100, blue 150, after calling swapRedGreen on that pixel its new RGB values would be red 100, green 255, blue 150. This function should swap the red and green values of the pixel. Then, go to and connect your GitHub account.Ĭreate a new project from GitHub, and select the repo you just created. Write a JavaScript function named swapRedGreen with one parameter pixel (representing a single pixel). You can host your app at the edge with Deno Deploy, our multi-tenantįirst, create a GitHub repo containing main.ts. Points newInstance 's Prototype to the constructor function's prototype property, if the prototype is an Object. new operator - JavaScript MDN new operator The new operator lets developers create an instance of a user-defined object type or of one of the built-in object types that has a constructor function. appendChild () returns the newly appended element. For convenience, let's call it newInstance. element.appendChild (new Image ()).src 'img/System/lifeIcon.png' This works because. new will do the following things: Creates a blank, plain JavaScript object. You have a working image resizer! Deploying to Deno Deploy When a function is called with the new keyword, the function will be used as a constructor. That is it! Now, if you want to try your API, just runĭeno run -allow-net main.ts, as we did before, and access it using a URLĬontaining the width, height, image URL, and mode.
