+## Module imports supported on mainnet - 2024-01-12
+
+- You can use external module imports with Chainlink Functions source code on mainnet networks. See the [Using Imports with Functions](/chainlink-functions/tutorials/importing-packages) tutorial to see an example of how to import and use imported modules with your Functions source code. This feature requires the [Functions Toolkit NPM package](https://www.npmjs.com/package/@chainlink/functions-toolkit/v/0.2.7) `v0.2.7` or later.

+The request requires a few modifications to work in the Chainlink Functions environment. For example, the `JsonRpcProvider` class must be inherited to override the JsonRpcProvider [`_send` method](https://docs.ethers.org/v6/api/providers/jsonrpc/#JsonRpcProvider). This customization is necessary because Deno does not natively support Node.js modules like [http](https://nodejs.org/api/http.html) or [https](https://nodejs.org/api/https.html). We override the `_send` method to use the [fetch API](https://deno.land/[email protected]?s=fetch), which is the standard way to make HTTP(s) requests in Deno. **Note**: The `url` passed in the constructor is the URL of the JSON RPC provider.

   Functions requests with custom source code can use vanilla [Deno](https://deno.com/). Import statements and imported
   modules are supported only on testnets. You cannot use any require statements.
+
+  It is important to understand that importing an NPM package into Deno does not automatically ensure full compatibility. Deno and Node.js have distinct architectures and module systems. While some NPM packages might function without issues, others may need modifications or overrides, especially those relying on Node.js-specific APIs or features Deno does not support.
