QUESTION
I am encountering an error with ESLint when attempting to deploy my functions to firebase. Specifically, it seems it is not liking arrow functions when I thought firebase supported arrow functions. I am using the ESLint provided by default initializing the functions files using firebase init functions.
ANSWER
Answered 2022-Feb-25 at 11:59I have tested this and I confirm that there are two things you definitely need, to fix the issue you are facing, would be to change in your package.json the scripts section to the following:
"scripts": { "lint": "eslint", ... } instead of “scripts”: {“lint”:”eslint .”, …} which is default.
So, removing the . from there, which is auto-generated but might cause this kind of issues.
Arrow functions are an ES6 feature, but here you have an async arrow function. Async functions in general are an ES8 (or 2017) feature. Therefore you need to specify the change the ecmaVersion of the parser to version 8, so changing in your .eslintrc.js file to this:

QUESTION
I'm writing a schema that has multiple patternProperties elements. Is there a way to specify the precedence these patterns should be checked?
Given this schema:
...ANSWER
Answered 2022-Feb-08 at 18:09The specification doesn't indicate an order in which the patterns should be applied, so an implementation could do anything, from running them in sorted alphabetical order or any other ordering of its choosing.
However, all patterns that match each property must evaluate their subschemas, so the ordering that they are checked should not be significant. If you are finding that the implementation stops matching a particular property as soon as a matching pattern is found, that would be a bug that should be fixed.

Answered 2022-Jan-05 at 14:53Its not a breaking error, just means that some functionalities might not work as expected.

QUESTION
Trying to install dependencies below
...ANSWER
Answered 2022-Jan-13 at 20:11Those are peer dependencies, not actual dependencies. Here is a good article explaining the difference. Peer dependencies are just to let users know what versions of various packages your installed package is compatible with. You don't need to fix these issues, as they are just letting you know which versions of various packages are compatible IF you want to use those packages sometime in the future.
In short, you can just start you project as-is, there is nothing that needs fixing.
