node-fetch VS jest

node-fetch.

To execute the algorithm, we will use Node.js (for the JavaScript runtime) and node-fetch (for network requests). This means we will run the code locally from the command line. For this project, we will have an output folder to store all the README data, as well as a list (queue) of repository URLs to visit. Before diving into the code, it is important to plan the input and output of the algorithm. For this web crawler, we will start at a valid GitHub repository page, which would be one URL string. After visiting each page with a README, we will export the data into a new file. Now lets cover the process of requesting a repository page from a URL. For this, we only care about saving the README file that is displayed, and we will ignore any other links that GitHub displays (such as the navbar). We will send a URL request with node-fetch, and retrieve the result of a HTML string. If we convert the HTML string to a DOM Tree, we can search for a specific element. GitHub stores the README file under a div with the class "markdown-body". We can use a library called 'jsdom' to use Browser API methods, and return a specific node.

Note: In case you run into install reference error: fetch isn’t defined, ensure you install node-fetch

Node Fetch is a JavaScript library tailored for Node.js that simplifies making HTTP requests. It offers a straightforward and Promise-based approach for fetching resources from the internet or server, such as GET, POST, PUT, and DELETE requests. Designed for server-side applications, it's compatible with the Fetch API, allowing easy code transition between client-side and server-side environments.

Would anyone be interested in an article about the crusade to move JS to ESM? I've been considering writing one, here's a preview:

Sindresorus wrote a gist "Pure ESM modules"[0] and converted all his modules to Pure ESM, breaking anyone `require`ing his code; he later locked the thread to prevent people from complaining. node-fetch released a pure ESM version a year ago that is 16x less popular than the CommonJS version[1]. The results of these changes broke a lot of code and resulted in many hours of developers figuring out how make their projects compatible with Pure ESM modules (or decide to ignore them and use old CommonJS versions)--not to mention the tons of pointless drama on GitHub issues.

Meanwhile, TC-39 member Matteo Collima advocated a moderate approach dependent on where your module will be run [2]. So the crusade is led not by the Church, but by a handful of zealots dedicated to establishing ESM supremacy for unclear reasons (note how Sindresorus' gist lacks any justifications). It's kind of like the Python 2 to 3 move except with even less rationale and not driven by the core devs.

https://www.npmjs.com/package/node-fetch is pretty standard assuming you're referring to an HTTP client library

The API is CORS-enabled, meaning you’ll have to use the getArticles() functions from your backend. For making the actual request, you can use the fetch() function, available since Node.js v18. For older versions of Node.js, you can use a fetch()-compatible library like node-fetch.

I have the same setup. On node 18 fetch would not go through. I changed 127.0.0.1 to localhost in my config/env. More info here

I am making a bot that is supposed to take data from Upland's database from the account "dcrawtu15ye". I am using autocode to take it and I have found some ways to use it but some of my code still comes back as null. I have been using the eos docs to find info and all it can do right now is get account info if I use console.log(await rpc.get_account('dcrawtu1u5ye'));. I am using the dependency node-fetch. I wanted to know if there is something wrong with the code below. I also used greymass from this list and this article supposedly might help too.

The RSS feed's URL will then need to be requested over the network. The native fetch API of JavaScript will be used since it is the most efficient. It undoubtedly works in browsers, and it appears that Node has a pretty well-liked implementation of it.

There are several testing approaches you can take to ascertain the functionality of the auth API. One way would be to automate the testing using unit tests with tools like Jest and Supertest. Alternatively, you can make use of API clients like Postman or the Thunder Client VS Code extension to test the API.

Jest

you have selected a testing framework. In my case, it's Jest with Supertest

Jest, created and maintained by Facebook, is a JavaScript testing framework with a focus on simplicity. It is often recognized for its zero-configuration setup and seamless integration, especially with React applications, making it a favored choice for developers in both small-scale projects and large enterprise applications.

Jest (https://jestjs.io/)

console.error Jest encountered an unexpected token Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax. Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration. By default "node\_modules" folder is ignored by transformers. Here's what you can do: • If you are trying to use ECMAScript Modules, see https://jestjs.io/docs/ecmascript-modules for how to enable it. • If you are trying to use TypeScript, see https://jestjs.io/docs/getting-started#using-typescript • To have some of your "node\_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config. • If you need a custom transformation specify a "transform" option in your config. • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option. You'll find more details and examples of these config options in the docs: https://jestjs.io/docs/configuration For information about custom transformations, see: https://jestjs.io/docs/code-transformation

Note: I will be using Jest as testing framework throughout the examples.

We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!

Jest has long been my favorite got to test runner when it comes to UI unit and integration testing. With tools like React Testing Library (Testing Library framework for React) you get the benefit of very easy to write and maintain tests, as well as a quick and efficient way to run our tests.
