Encountered an issue with importing a JavaScript library in TypeScript

I am trying to import a JavaScript library called Akarata. I have followed the suggestions from the internet, such as:

import * as akarata from 'akarata/dist';

or

import * as akarata from 'akarata';

However, I am still encountering an error:

Try npm install @types/akarata if it exists or add a new declaration (.d.ts) file containing declare module 'akarata';

I have tried these solutions but nothing seems to work.

What's strange is that when I first type ng serve (as I'm using Angular), the error appears. But after making some changes to my project and saving them, the error persists even though my project works fine and the library functions correctly.

Does anyone know why this is happening?

Answer №1

TypeScript is a powerful extension of JavaScript that translates into regular JavaScript code. With TypeScript, you can add type definitions to your variables and functions, making your code more robust and easier to maintain. If you're using an external library like akarata, you will need to provide type declarations for TypeScript compatibility. Some libraries come with their own typing files, while others may require manual installation.

If a library lacks a .d.ts file, it's recommended to install it yourself in order to seamlessly integrate it with TypeScript and Angular applications.

Here’s a solution:
Check if the src/typings.d.ts file exists. If not, create it and declare your package within it:

declare module 'akarata'

Don’t forget to import it in your code:

import * as akarata from 'akarata';

Answer №2

Make sure to include the following code in your angular-cli.json configuration file.

"scripts": [
    "../path"
];

Next, add the declaration in typings.d.ts:

declare var akarata:any;
