Imagine we have a foo.js file containing a variable, function, and class that are not yet part of the project.
Now suppose we want to access these elements in our home.ts method or make them globally available for use within a home.ts method. How can this be accomplished?
When working in your foo.ts file, you may have a function like this:
myfunt(){
//your logic goes here
}
If you want to utilize this function in your home.ts file, follow these steps:
Step 1: Import your foo.ts file in home.ts
Step 2: Your export class should be structured as follows
export class home extends foo {
// By using the extends keyword, you unlock all the data from the foo.ts file for use in home.ts
// Now you can try to access the myfunt() function
constructor(){
super.myfunt(); // Use the super keyword to access all the available data in the foo.ts file
}
}
To utilize definition files (.d.ts), follow these steps:
Start by verifying if a definition file for foo.js already exists within the community. You can check it out here: or here https://github.com/DefinitelyTyped/DefinitelyTyped
If the file does exist, you can install it using this command:
npm install --save @types/foo
If not, you have the option to create your own definition file for this javascript file.
Name the file foo.d.ts and include content like this:
declare var data:any;
declare function myFunc(n:string);
Once created, you can treat it like a usual ".ts" file.
import * as foo from "./foo"; //"./foo" indicates the path to your .d.ts file.
foo.myFunc()
