RuntimeError with WebAssembly in @react-pdf/yoga on Node.js Server

[gino8080]

Hello,

I've encountered a critical issue while using @react-pdf/renderer in a Node.js Express server environment. The server crashes with a RuntimeError related to WebAssembly memory allocation when attempting to generate PDFs. The error message is as follows:

RuntimeError: Aborted(RangeError: WebAssembly.instantiate(): Out of memory: wasm memory). Build with -sASSERTIONS for more info.
    at w (/usr/app/node_modules/yoga-layout/binaries/wasm-async-node.js:14:73)
    at /usr/app/node_modules/yoga-layout/binaries/wasm-async-node.js:62:60

This error suggests that the WebAssembly module within yoga-layout, which is a dependency of @react-pdf/renderer, is running out of memory.

To Reproduce

1. Set up a basic Express server that uses @react-pdf/renderer to generate PDFs.
2. Trigger the PDF generation endpoint with the necessary data.
3. The server crashes with the above RuntimeError after a few successful PDF generations. Expected Behavior:

The PDF generation should complete successfully without causing a server crash or running out of WebAssembly memory.

Actual Behavior:

The server crashes with a RuntimeError indicating that WebAssembly ran out of memory.

Additional Context:

The issue seems to occur after generating multiple PDFs, suggesting a potential memory leak or insufficient memory allocation for WebAssembly in the yoga-layout module. Reducing the complexity of the PDF layout temporarily mitigates the issue but does not solve it entirely. I would appreciate any insights or suggestions on how to resolve this issue. If there are any known workarounds or if additional information is needed, please let me know.

Environment:

Node.js version: v16.18.1 Express version: ^4.18.2 @react-pdf/layout": "3.10.3", @react-pdf/renderer": "3.3.4", Operating System: docker image

Thank you for your time and assistance.

Hey I have the same problem.

Did you try to use other version of @react-pdf/layout? I'm still searching a solution but dint find one at the moment.

Switch back to 1.6.8 was the only thing which helps....
