I need a TypeScript library to, format money and numbers, perform localization operations

Question

I'm developing a mobile application using React-Native and TypeScript super-set. I am looking for a format library in which I can perform numbers, currencies, dates, numbers and localizations.

I've used the Numeral JS library before, but the format range is too narrow, and I tried the autoNumeric library, but I didn't have the possibility to use it because @types was not available.

Apart from this, I did not get the efficiency I wanted from many libraries. I'd love to hear your suggestions.

Answer 1

Even if @types is not available you can still use the autoNumeric library by adding your own type definition.

1. Add a @types folder inside project folder
2. Create a file named .d.ts

3. Inside the file add the following line

   declare module 'autonumeric';

4. Add the path of the newly created folder in tsconfig.json under compilerOptions like so

   "typeRoots": ["node_modules/@types", "src/@types"]

   Note: "node_modules/@types" will already be present. You only need to add the newly path of the new folder.

5. Save. Run npm i and then start the application.
