This example demonstrates a promise-based HTTP wrapper for fetching data from the JSONPlaceholder API. The code defines a `makeRequest` function that constructs a request path from user-supplied command-line arguments, using Node’s built-in `http` module to send a GET request to `jsonplaceholder.typicode.com`. It parses the response body as JSON and resolves the promise with the parsed data, while rejecting with an error message for non-200 status codes. The module exports the function for reuse.

This example demonstrates JavaScript Promise patterns for asynchronous server communication, showing fetch(), .then(), .catch(), Promise.all/race, custom Promise construction, and async/await syntax. The code samples use the browser's built-in fetch() API against document.URL.toString() to simulate server checks, with console.log output for results and error handling. It also includes a setTimeout-based delay Promise example to illustrate timing control. The gist serves as educational reference material, contrasting Promise chains, custom Promise creation, and sugar-syntax async functions.

This example demonstrates asynchronous file reading and HTTP request handling in Node.js. It shows how to extract the first line from a local file and retrieve the HTTP status code from a remote URL using two separate promise-based functions. The code uses Bluebird’s `Promise` constructor, Node’s `fs.readFile` API, and the `request` library for network requests. Each function returns a promise that resolves with the extracted data or rejects on error, illustrating a modular approach to handling I/O operations with promise chaining.

This example shows a JavaScript promise used to model a conditional request for a new phone. The code defines a `Promise` constructor that resolves with a phone object when a boolean flag `isMonHappy` is true, and rejects with an error otherwise. The `askMon` function calls the promise, chaining `.then()` to log the resolved phone details and `.catch()` to log the rejection message. The demonstration relies solely on native promise syntax and `console.log` for output, with no external libraries or rendering.

This example contrasts two JavaScript approaches for fetching GitHub user data from the GitHub REST API. It uses the Fetch API to request `https://api.github.com/users/mistyblunch` and logs the resulting JSON. The first method chains `.then()` callbacks in a Promise-based function, while the second defines an `async` function that uses `await` to handle the response and return the parsed JSON object. Neither function performs any visualization or rendering—only console output.

fetching data

This example shows a bare-bones HTML page that fetches data from a remote URL. It demonstrates the basic Fetch API workflow in JavaScript, where a `fetch()` call is made to a GitHub Gist URL and a promise is created to handle the response. The page includes a static "Hello HTML!" message and sets up the foundation for asynchronous data loading, though the response handling is incomplete. The example uses plain HTML, CSS for styling, and JavaScript's built-in `fetch()` function, with no external libraries or visualization components yet.

This example demonstrates a lightweight Express server that acts as a CORS proxy for a joke API, enabling browser-based requests to bypass cross-origin restrictions. The code uses the `express` and `request` libraries to define a route, `/jokes/random`, which forwards requests to `https://joke-api-strict-cors.appspot.com/jokes/random` and relays the JSON response back to the client. A middleware sets the `Access-Control-Allow-Origin` header to `*`, allowing any frontend to access the proxied data. The server listens on a configurable port, defaulting to 3000, and handles errors by returning a JSON error object. This setup illustrates a simple server-side solution for enabling client-side data fetching from a restricted external source.

This example demonstrates a Node.js utility that asynchronously fetches the HTTP status code for a given URL. It first reads a text file using the `fs.readFile` method to extract a domain or URL from its first line, then passes that address to the `request` library’s `getStatusCodeAsync` function, which returns the server’s response code. The visualization shows how file I/O and network requests are chained through callbacks, highlighting the flow of data from local storage to remote servers without any graphical rendering.

Fork of Promise function practise

This example demonstrates a minimal HTML page that fetches COVID-19 daily report data from a GitHub-hosted CSV file using the Fetch API and async/await syntax. The `fetchText` function retrieves the raw CSV text and passes it to a placeholder `<Chart data={res} />` component, though the chart itself is not implemented. The page displays static text “Hello HTML” alongside commented-out CSS styling, and relies on React for rendering, though no actual visualization or data processing occurs beyond the network request and console logging.
