try-catch-decorator v1.0.4

try-catch-decorator

A TypeScript decorator to wrap methods with a try-catch block.

Step 1: Installation

You can install the package via npm:

npm install try-catch-decorator

Step 2: Update tsconfig.json

After installing the package, you need to enable the experimentalDecorators option in your tsconfig.json file to use decorators in TypeScript.

Add the following line to your tsconfig.json:

{
    "compilerOptions": {
        "experimentalDecorators": true
    }
}

Usage Example

Consider a scenario where you have an async method fetchData within a class DataFetcher, which fetches data from an external API using await. You want to ensure any errors during this asynchronous operation are handled gracefully.

import { tryCatch } from 'try-catch-decorator';

class DataFetcher {
    @tryCatch
    async fetchData() {
        // Fetch data from an API
        const response = await fetch('https://api.example.com/data');
        const data = await response.json();
        // Process the data
        return data;
    }
}
