imports_map.json no longer respected

[FallingSnow]

The hello example no longer works. This may be caused by a cache issue?
Issue is the same with aleph@v0.3.0-alpha.4.

The interesting thing about this is it kind of half worked before I did rm -rf .aleph, then all the modules errored (as opposed to like half of them).

fixed! thank you @FallingSnow

aleph upgrade

[FallingSnow]

Doesn't seem entirely robust.

If you don't add something to imports_map.json and end up getting:

ERROR module '/pages/pipeline/graphql-tag' not found

you can't just add it to the map and run aleph dev again, it will produce the same error. You need to run

$ rm -rf .aleph
$ aleph dev

and then it will download correctly.

[ije]

that is because the previous compilation cache is still on your disk, you can run the server with reload flag instead of removing the .aleph dir:

aleph dev --reload

[ije]

what content you added in the import_map.json actually?

[FallingSnow]

This what I added, not the full map.

{
    "imports": {
        "graphql-tag": "https://esm.sh/graphql-tag"
    },
    "scopes": {}
}

[ije]

after you change the aleph.config or the import maps you need to restart the server to make it works. i will improve this to restart automaticlly in the future.

[FallingSnow]

I restarted the server and the error persisted. It was only after clearing the cache that it went away.

[shadowtime2000]

So that means import maps are cached? I don't think that is something that should be done

[ije]

sorry @FallingSnow, i can't repeat your case. i only got the download message since it not versioned when restarted:

[FallingSnow]

Hmm, I'll see if I can reproduce.

[ije]

but yes, when the import maps changed, the relative compilation cache should be cleared!

[FallingSnow]

I was able to reproduce.
