Setting up modern monorepo with browser and node targets [v2]

[xzilja]

Sorry if this discussion ends up verbose, but this is my first experience with parcel and I am trying to figure out how to use it for a modern monorepo setup that targets browser / nodejs and exposes some shared modules.

1. Assuming we are starting with yarn workspaces and our structure is similar to below:

packages/
     app/
          index.tsx
          index.html
          package.json
     core/
          utilities.ts
     server/
           index.ts
package.json
tsconfig.json

2. What I did so far is add parcel to root package json and added start and build commands in app/package.json, so far so good. I then proceeded to set up aliases for these packages inside root package.json i.e.

{
  "alias": {
    "core": "packages/core/**/*",
    "app": "packages/app/**/*",
    "server": "packages/server/**/*"
  },
}

However when I tried to import utilities from "core/utilities" inside my app package, I got an error saying that this failed to resolve, so I assume I did something wrong here? I am also unable to use ~/packages/core/utilities, as it resolves incorrectly as well.

3. I paused with alias, and went on with reading the documentation. I think I need to specify target for each of my packages now, but I am not sure if I shold do it in individual package json files or in root one, furthermore I want to somehow make it so that my app only produces code necessary to run it in latest chrome / safari and my server needs to produce bundles for node v14. In terms of where I want too build this, a dist folder for each package (i.e. packages/app/dist) will work. Now how would I approach this to make it more managable?

Would appreciate any examples / deep dives into this if possible. Need to understand how to set things like targets / engines / browserlist here correctly and produce modern bundles, while also utilising features like alias for better dev experience

@iljadaderko did you end up figuring out this set-up, and/or would you recommend a different route in 2022?
