opt-out of logs?

[kentcdodds]

Is your feature request related to a problem? Please describe.

In my (edge) use case of having an app where we're pretending there really is a server even though there isn't. I'd prefer to not get anything logged to the console from MSW (unless there's an error).

Describe the solution you'd like

I'd like to be able to disable the logging. Perhaps as an option when I call start?

Describe alternatives you've considered

I'm considering overriding console.log/etc to filter out MSW logs.

I think this makes sense, the ability to opt-out of logs was voiced in the related ticket (), yet I've went with enabled by default.

Thinking out load, the arguments to the start() function may be adjusted as:

function start(options: StartOptions): Promise<ServiceWorkerRegistration| null>

interface StartOptions {
  serviceWorker: {
    url: string
    options: string
  }
  quiet: boolean
}

It will be possible to opt out of logs in the next release (0.14.0):

import { composeMocks } from 'msw'

const { start } = composeMocks(...)
start({ quiet: true })

Awesome! Thank you :)

@kentcdodds, could you please update to 0.14.0 and let me know that using the quiet: true option does what you need?

As always, there's an integrity bump ;) This release contains a bunch of other fixes, one of which affects the Service Worker module.

Just tried and running npx msw init public doesn't update my service worker 😬

Also, just noticed that this doesn't silence the first log that says [MSW] Mocking enabled.

I think I'd like all logs gone.

Oh, and I think the docs here need to be updated: https://redd.gitbook.io/msw/recipes/custom-service-worker-url :)

Originally, I wanted to leave the activation message intact, so it's always evident the page is handled by the mock service worker. However, since the quiet mode is explicit, I believe there's little harm done in silencing the activation message as well. I'll provide a pull request in a short notice.

Just tried and running npx msw init public doesn't update my service worker.

What version of msw are you using? (npm ls msw).

[kettanaito]

The activation message should now be silenced as well when using start({ quiet: true }).

Could you please update to 0.14.1 and let me know?

[kentcdodds]

0.14.1 works! Thanks!
