Easier Non-JavaScript Artifact Imports

The amount of data present in the world continues to grow exponentially with time. This huge amount of data exists in many different types. These data can be text files, images, videos, audios, etc. Furthermore, these data can be stored in several file formats as well. A file format is a standard way in which data is encoded to be stored on a file storage system. There are numerous file formats such as HTML, JSON, XML, JPEG, PNG, MP3, MP4, etc. Although the format is different from one another, the core concept is the data. In order to use this data which exists in several file formats, we needed a way to import them to our JavaScript applications safely. Import Assertion is such a proposal we will be discussing about today.

What is Import Assertion?

Import Assertion is a proposal that allows for additional metadata to be passed alongside import modules.

In web development, there was a need to import data that exist in various forms into our JavaScript code. This was especially much needed with JSON data types as it was very common amongst modern web developers as it was served as a replacement for XML in AJAX applications.

According to the development team, this was a core reason for the introduction of the import assertion proposal. According to the proposal, a JSON module will be imported as shown below.

import json from "./foo.json" assert { type: "json" };
import("foo.json", { assert: { type: "json" } });

Now you might start wondering, why we cannot import JSON modules as simple as,

import json from "./data.json";
