That looks like this: Our RSS parser in NodeĪnd in plain text, it looks like this: Parsing If you run it, you should see the title of the feed, followed by the title and link of each item in the feed. To run the parser, run the following command: node index.js Now that you understand how the parser works, let's run it. Then we are logging the title of each item in the feed along with the link to the item. This is the title of the feed itself, and is the first thing that will be displayed after the RSS feed is parsed. The await keyword is used to wait for the promise to resolve.įinally when the promise is resolved, we're logging the title of the feed. This method takes in a single argument, url, and returns a promise, which we are awaiting. We're using the parseURL method to parse the feed. Inside the parse function, we're using our RSSParser from the rss-parser library to parse the RSS feed. In this case, we are parsing the RSS feed of this very website, but you can parse any RSS feed you want. Next, we're creating a function called parse that will take in a single argument, url, and will parse the RSS feed. Next, we're creating a variable called feedUrl that will hold the URL of our RSS feed. This is the library that we will use to parse our RSS feed. First, we're requiring the rss-parser npm package. Add the following code to the file: import RSSParser from "rss-parser" Ĭonst feed = await new RSSParser().parseURL(url) Ĭonsole.log(`$\n\n`)
Create a file called index.js in the root of our project. With our npm dependencies installed, we can now write our parser. Once you've done that, we are ready to write our parser. Or using npm, you can install it like this: npm install rss-parser Now let's install rss-parser, the library we will use to parse our RSS feed. Feel free to change the name of the project, but we'll keep it as app. This will create a package.json file for you. Run the following command to initialize the project: npm init -y This will create a package.json file in the root of our project. Since this is a Node project, we will need to initialize it as an npm package.
