I'm trying to setup SSR for react app with @loadable/components
. I setup all based on docs with babel and webpack plugins. When I try to run node server.js
it runs ok but when I open a browser and throws the following error (into node console):
TypeError [ERR_INVALID_ARG_TYPE]: The "id" argument must be of type string. Received an instance of Object

}
As you can see there is @MYSCOPE in the traceback which holds some of my internal packages (if it matters).
@loadable/server/lib/util.js
is the following function:
And when I try to console.log(modulePath)
on line 42 I see a whole stats JSON output which seems wrong and I should get a single module path (as I understand).
Any help?
I can share some specific parts of my configuration files if needed. Because I see my own package in console output seems like something is wrong with it's build (it works perfectly on the client-side with cjs build), but having full stats object as module path is very confusing.
UPD: Demo https://www.dropbox.com/s/9r947cgg4qvqbu4/loadable-test.zip?dl=0
Run
yarn
yarn dev:server
# go to localhost:3000 and see the error in console
to rebuild:
yarn
yarn dev:build-client
yarn dev:build-server
yarn dev:server # go to localhost:3000
The
statsFile
option passed toChunkExtractor
expects a path to theloadable-stats.json
file, not the actual JSON content of it. By doingrequire('../loadable-stats.json')
, webpack actually resolve the JSON during build time and assign it to theloadableJson
variable.You can change your
loadableJson
as follow:This will solve the problem you had on your question. But, if you only do this, you will notice that you have another problem. Loadable by default assumes that your entry chunk name is
main
. This is not the case in your demo, as you have set the entry chunk name to beapp
instead.To solve this, simply tell loadable about your
entrypoints
names by passing an array to theChunkExtractor
contructor as such:That's it, everything should now be working properly!
If it helps, I set up the demo on GitHub so you can easily see the changes I made here.
