how to escape dots

[opensas]

I want to programmatically enter the following settings in my package.json file

  "jest": {
    "transform": {
      "^.+\\.svelte$": "svelte-jester",
      "^.+\\.js$": "babel-jest"
    }
  },

Yeap, it doesn't seem easy at all...

I tried with:

$ npx npe 'jest.transform.^.+\\.svelte$' "svelte-jester"

and I get

  "jest5": {
    "transform": {
      "^": {
        "+\\\\": {
          "svelte$": "svelte-jester"
        }
      }
    }
  }

Any way to achieve it?

Any way to tell npe to treat . as part of the key?

And how about the slashes that are being duplicated?

this is the workaround I found so far:

npx npe 'jest.transform.__svelte-reg-exp__' "svelte-jester"
sed -i 's/__svelte-reg-exp__/^.+\\\\.svelte$/g' package.json
npx npe 'jest.transform.__js-reg-exp__' "babel-jest"
sed -i 's/__js-reg-exp__/^.+\\\\.js$/g' package.json

That's a tricky one! You might be better off writing something custom for this use case, or sticking with this sed workaround :)
