How to Populate HTML Dynamically with Data from An API
- Working with APIs is essential for web developers and in this article, we learn how to display data from an API on a webpage.
- The data accessed through APIs is stored on a remote server that can be accessed using the fetch() method in JavaScript.
- To populate data on a certain part of a webpage, the developer must fetch the required data and display it using various JavaScript methods.
- The developer first assigns the part of the HTML document that needs to be populated with a variable.
- Then, the developer assigns the URL of the API to a variable and creates an asynchronous function to retrieve and process the data.
- The developer uses conditional statements and loops to filter the data according to specific criteria and returns an iterable array containing filtered data objects.
- The developer then uses another asynchronous function to populate the webpage with the retrieved API data using the previously declared container variable and various string concatenation rules.
- The function generated HTML elements with data from each filtered item while iterating through the array.
- The output is then dynamically displayed on the page, and the content is updated in real-time as the data in the API changes.
- In conclusion, using APIs to display data on webpages is a task that every web developer needs to know, and this article provides a simple guideline to achieve this task effortlessly. Note that content can be filtered or manipulated according to the developer's preferences and that deep understanding of JavaScript data manipulation is essential.
