Can't use Faker with k6

[pawfectQA]

Clear and concise description of the problem

As a QA using faker I wish that I could use updated faker with k6 scripts. Now I get an error, that k6 doesn't support this module. I import it as import { faker } from "@faker-js/faker";, and when I run tests, I get this message: GoError: The moduleSpecifier "@faker-js/faker" couldn't be recognised as something k6 supports.
at go.k6.io/k6/js.(*requireImpl).require-fm (native)

Suggested solution

Maybe this helps somehow k6 docs

Thank you for your feature proposal.

We marked it as "waiting for user interest" for now to gather some feedback from our community:

• If you would like to see this feature be implemented, please react to the description with an up-vote (:+1:).
• If you have a suggestion or want to point out some special cases that need to be considered, please leave a comment, so we are aware about them.

We would also like to hear about other community members' use cases for the feature to give us a better understanding of their potential implicit or explicit requirements.

We will start the implementation based on:

• the number of votes (:+1:) and comments
• the relevance for the ecosystem
• availability of alternatives and workarounds
• and the complexity of the requested feature

We do this because:

• There are plenty of languages/countries out there and we would like to ensure that every method can cover all or almost all of them.
• Every feature we add to faker has "costs" associated to it:
  • initial costs: design, implementation, reviews, documentation
  • running costs: awareness of the feature itself, more complex module structure, increased bundle size, more work during refactors

test issue.zip
the code itself can be with mistakes, but it lets test the issue. Thank you!

@pawfectQA Thanks for providing the zip. Which version of k6 are you using?
I know you have included the exe in the zip, but I cannot verify its integrity as it seems to be an older version.

EDIT: ⚠️ The checksums of the zipped and the v0.49 from github don't match.

[ST-DDT]

Have you tried with the latest version of k6 as well?

[pawfectQA]

I use v0.49 of k6

[pawfectQA]

I tried the latest version and it has the same issue.

[pawfectQA]

the zipped one may be lower version because it includes some extension 🧐 but I tried all the latest versions too

Instead of importing from @faker-js/faker try https://cdn.jsdelivr.net/npm/@faker-js/faker@8.4.1/dist/esm/locale/en.mjs

or adding a package.json with @faker-js/faker as depedency and run npm install and then use ./node_modules/@faker-js/faker.

[ST-DDT]

Does that help you/fix the issues you have?

[pawfectQA]

It says: WARN[0002] The source for https://cdn.jsdelivr.net/npm/@faker-js/faker@8.4.1/dist/esm/chunk-LSZKOVGW.mjs needs to go through babel but is over 256000 bytes. For performance reasons source map support will be disabled for this particular file.

Still investigating

and the second method gave me "node_modules@faker-js\faker: Incorrect function."

You might have to adjust the path to match your actual file system.

Did you have any luck getting this to work?
