refactor(dpp): using deprecated param to init wasm module

[shumkov]

Issue being fixed or feature implemented

When wasm-dpp is initialized we see:

using deprecated parameters for `initSync()`; pass a single object instead

What was done?

• Use new way to pass the wasm module bytes to the initSync function

Walkthrough

The pull request introduces a modification to the loadDppModule function in the packages/wasm-dpp/lib/index.ts file. The change involves updating the argument passed to dpp_module.initSync() from a direct bytes parameter to an object with a module property containing the bytes. This subtle change alters how the WebAssembly module initialization data is structured, potentially reflecting updates in the module's initialization requirements.

Poem

🐰 A rabbit's tale of WASM delight,
Where bytes now dance in module's might,
Initialization with a twist so neat,
A subtle change, now code complete!
WebAssembly modules, hop and sing! 🚀

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

38-39: Consider adding error handling.

The initialization could potentially fail, but there's no error handling. Consider wrapping this in a try-catch block to handle initialization failures gracefully.

-    dpp_module.initSync({ module: bytes });
+    try {
+      dpp_module.initSync({ module: bytes });
+    } catch (error) {
+      throw new Error(`Failed to initialize DPP WASM module: ${error.message}`);
+    }

Line range hint 1-40: Consider improving type safety.

The file uses several TypeScript ignores which might hide potential type issues. Consider:

1. Adding proper types for the wasm imports
2. Using proper WebAssembly types for the binary data

-// @ts-ignore
-import wasmBase from './wasm/wasm_dpp_bg';
+import { WebAssembly } from '@types/webassembly-js-api';
+import wasmBase from './wasm/wasm_dpp_bg';

-let bytes = Buffer.from(wasmBase, 'base64');
+let bytes: Buffer | Uint8Array = Buffer.from(wasmBase, 'base64');

38-38: LGTM! Parameter style updated correctly.

The change properly addresses the deprecated parameter warning by updating to the new object-style parameter format.

---

38-38: Verify WASM module interface compatibility.

Let's verify that this change matches the expected interface of the wasm-dpp module.

✅ Verification successful

Based on the gathered information from the shell scripts, I can now provide a final response:

WASM module initialization appears to be correctly implemented

The code shows two initialization patterns being used consistently:

• Async initialization using init(wasmUrl) for browser environments
• Sync initialization using initSync({ module: bytes }) for non-browser environments

The implementation aligns with the wasm-bindgen patterns and the project's build configuration confirms WASM target support.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check the wasm-dpp module interface

# Look for other initSync usages to confirm the parameter pattern
rg -A 2 "initSync.*module.*bytes" 

# Check for any documentation or type definitions
fd -e d.ts -x cat {} \; | rg "initSync"

Script:

# Let's check the WASM module interface more thoroughly

# Look for type definitions or interfaces related to the WASM module

# Search for any WASM initialization patterns
rg -B 2 -A 2 "initSync|init.*wasm" 

# Look for any documentation or comments about WASM initialization
