javascript - parcel serve returnerar index.html för SourceMap-förfrågningar och icke existerande URL:er

Enkel vanilla TypeScript-utvecklingsmiljö uppsatt med Parcel.

Jag har ingen SourceMap i webbläsaren (Edge/Chrome):

DevTools failed to load SourceMap: Could not parse content for http://localhost:1234/index.7cacc1f4.js.map: Unexpected token < in JSON at position 0

paket tjänst logg efter sidladdning:

parcel serve ./src/index.html --log-level verbose
ℹ️ Server running at http://localhost:1234
✨ Built in 3.15s
@parcel/reporter-dev-server: Request: localhost:1234/
@parcel/reporter-dev-server: Request: localhost:1234/index.7cacc1f4.js

@parcel/reporter-dev-server: Request: localhost:1234/favicon-32x32.232ca4f5.png

SourceMap-filen finns i dist:

ls dist
__                              favicon-32x32.232ca4f5.png      index.453c97a0.js.map

apple-touch-icon.e80caf23.png   index.031565ba.js               index.7cacc1f4.js.map
favicon-16x16.bc10cd1f.png      index.031565ba.js.map           index.html
favicon-16x16.d41cdce3.png      index.453c97a0.js

Det verkar som att parcel serve returnerar indexsidan istället för SourceMaps:

curl -v localhost:1234/index.7cacc1f4.js.map 
*   Trying ::1...
* TCP_NODELAY set
* Connected to localhost (::1) port 1234 (#0)

paketlogg från curl ovan:

@parcel/reporter-dev-server: Request: localhost:1234/index.7cacc1f4.js.map

parcelversion: 2.0.0-beta.2

Det är också konstigt att parcel serve inte returnerar 404 utan bara omdirigerar till index när sidan inte hittas?

Svar #1

Det är en bugg i parcel 2, men redan fixad i den aktuella nattliga versionen: https://github.com/parcel-bundler/parcel/issues/6078
