Attempting to implement the big.js library, with its definition available here.
The following line functions properly:
const CONSTANT_1 = new Big(0);
However, this line:
const CONSTANT_2 : Big = new Big(0);
Results in the following error message:
error TS2304: Cannot find name 'Big'.
What could be causing this issue?
Consider the implicit type of the first one:
https://i.sstatic.net/Ge2p6.png
Issue
The reason why this approach fails...
const CONSTANT_2: Big = new Big(0);
...is due to Big being defined as a variable rather than a type in the definition file:
declare var Big: BigJsLibrary.BigJS;
Resolution
To utilize explicit typing, you must reference the constructor's created type...
const CONSTANT_2: BigJsLibrary.BigJS = new Big(0);
...as demonstrated in the definition file below:
interface BigJS_Constructors {
new (value: number): BigJS;
// etc...
}
