Moon enforce use bun when the task command start with bun

[harrytran998]

Currently, in our project, we use pnpm for package manager, bun for cli tools.
When doing something with the application, like dev or build --> Use pnpm, --> Correct!

But with some special applications, we want to use bun as a runtime. So we need to write like below. When config like bunx or bun something --> Moon enforce run bun install first. So, do you have any suggestions here @milesj ?

tasks:
  build:
    command: "react-router build"

  dev:
    command: "bunx --bun vite"

I tried this way --> can work, but feel quite hacky/workaround.

  dev:
    command: "pnpm bun --bun vite" 

Note:

• Moon latest version

[milesj]

@harrytran998 Is bun enabled in the toolchain? https://moonrepo.dev/docs/guides/javascript/bun-handbook#enabling-the-language

With that said, having bun and pnpm both install dependencies in the same project is very problematic, as node_modules will collide.

[harrytran998]

Quite fun, the result is: both run together :))

pnpm install (in workspace)
bun install (in workspace)

[milesj]

Yeah that's pretty much expected.

If it causes issues, you can configure this setting: https://moonrepo.dev/docs/config/workspace#installdependencies

I added the pipeline --> installDependencies: ['pmpm'] or installDependencies: false Still have problem. I just have only 1 pipeline, but do not know why it was duplicated 🤔

pipeline and runner are the same thing, just aliases. Merge them together.

Also the toolchain is node not pnpm.

[harrytran998]

Worked!

runner:
  ...
  installDependencies: ["node"]

Thanks for taking the time to care about us! Appreciated 🙏🏻 @milesj Hope Moon will be exploding in the future!
