Anyone Running Temporal Typescript SDK on Bun?

[dhiaayachi]

I created the following issue over at Bun: https://github.com/oven-sh/bun/issues/12552

I wanted to see if anyone else in the Temporal community has had success running Temporal Typescript libraries on Bun? I'm getting a Rust crash and have outlined the error in the above mentioned issue. I figure this may be a Bun bug, but maybe there's a slight modification that can be made to the typescript libraries that increase compatibility with the Bun runtime?

It's great that you're exploring the possibility of running Temporal TypeScript libraries with Bun! While Bun is a promising JavaScript runtime, its compatibility with TypeScript libraries built for Node.js can be a bit tricky.

Here's a breakdown of your issue and potential solutions:

Understanding the Problem

The Rust crash you're experiencing likely stems from Bun's reliance on its own native implementation of JavaScript core features. These features are often implemented differently from how they are in Node.js, potentially leading to unexpected behavior or crashes when using libraries built for Node.js.

Potential Solutions and Considerations

• Bun's Compatibility: Bun is actively evolving its compatibility with Node.js libraries. While the current state might not be perfect, you can check the Bun documentation for updates on compatibility features and known issues.
• Library Modifications: Modifying the Temporal TypeScript libraries to increase Bun compatibility is generally not recommended. The libraries are carefully crafted to work within the Node.js ecosystem, and modifying them could lead to unexpected behavior or even break compatibility with Node.js itself.
• Temporal Community Feedback: Your observation is valuable! Posting your issue on the Temporal Community Forum could lead to insights from other developers who have attempted to run Temporal TypeScript libraries on Bun.
• Node.js as a Middleman: If you need to use the libraries within a Bun project, consider using a Node.js process as a middleman. This could involve:
  • Creating a small Node.js application that uses the Temporal libraries and communicates with your Bun application via a network protocol (e.g., gRPC, HTTP).
  • Using a module bundler like Webpack or Parcel to bundle the Temporal libraries for compatibility with Bun.
  • Explore libraries like Bun-Worker to create a Node.js worker running inside Bun.

Important Considerations

• Stability: Bun is still in its early stages of development. While its performance and feature set are impressive, there might be some instability or missing features that impact compatibility.
• Future Compatibility: Bun's development team is continuously improving compatibility with Node.js libraries. You can check their roadmap for updates.

Let me know if you have any further questions! Happy to help you navigate the world of Temporal and Bun!

Thank you for reporting this!

It seems like you are experiencing an issue with running Temporal Typescript libraries on Bun. You've created a Bun issue here: https://github.com/oven-sh/bun/issues/12552.

Could you please provide more context on the specific Temporal Typescript libraries you are using and the Bun version you are on? This will help me better understand the problem and potentially suggest a workaround or solution.

For example, could you share the relevant portions of your code, specifically how you are using the Temporal Typescript SDK in your Bun project?

Thanks for reporting the issue! I am unable to provide you with a solution based on the documentation you provided. The documentation does not mention Bun or any issues related to it. To be able to assist you better, could you provide more information on how you have set up your Bun project and what modifications you have tried to increase compatibility?

Thanks for reporting this issue. It appears that you are encountering a Rust crash while running Temporal Typescript libraries on Bun. It looks like this might be a bug in Bun, but based on our documentation, there is no slight modification to the Typescript libraries that can be made to increase compatibility with the Bun runtime. Let us know if you have any further questions.

Thanks for reporting this! It seems like you're encountering a compatibility issue between the Temporal Typescript SDK and Bun. Unfortunately, there's no specific documentation or known workarounds for using the Temporal Typescript SDK with Bun at this time.

Given that you've already opened an issue on the Bun repository, it's likely a Bun bug. The best way to resolve this issue may be to collaborate with the Bun maintainers.

You could try these suggestions in the meantime:

• Check for updates: Ensure both the Temporal SDK and Bun are up-to-date.
• Experiment with alternative approaches: Consider whether another Node.js runtime, like Deno or the official Node.js runtime, might be a suitable alternative for your project.

Let me know if you have any other questions.
