[domasx2]

Please answer these questions before submitting a bug report.

What version of OpenTelemetry are you using?

1.10

What version of Node are you using?

v14.18.3

Please provide the code you used to setup the OpenTelemetry SDK

import { registerInstrumentations } from '@opentelemetry/instrumentation';
import { DocumentLoadInstrumentation } from '@opentelemetry/instrumentation-document-load';
import { ConsoleSpanExporter, SimpleSpanProcessor } from '@opentelemetry/sdk-trace-base';
import { WebTracerProvider } from '@opentelemetry/sdk-trace-web';

const provider = new WebTracerProvider();
provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));

registerInstrumentations({
  instrumentations: [new DocumentLoadInstrumentation()],
});

What did you do?

• Installed latest (1.1.0) version of otel deps
• Added example setup snippet
• Tried to build app (using Parcel)

What did you expect to see?

I expected my app to build

What did you see instead?

Error:

@parcel/resolver-default: Could not load './build/esm/index.js' from module
'@opentelemetry/sdk-trace-web' found in package.json#module
  /Users/bogdan/Workspace/Grafana/grafana-javascript-agent/node_modules/@opentelemetry/sdk-trace-web/package.json:6:13

    8 |   "types": "build/src/index.d.ts",

It seems most @opentelemtry packages only have build/src, but are missing esm and esnext builds.

Additional context

Quick investigation found:

• Each package has a tsconfig.all.json that would build all versions of the package
• Root compile command uses ts --build
• Root tsconfig.json has references to each package directory only, thus each package is built using it's default tsconfig.json which only builds the commonjs module. Therein lies the issue

Possible solutions:

• modify root tsconfig.json references to point to tsconfig.all.json for each package
• Modify root compile command to lerna run compile instead of ts --build
