- we have our own error library that should always be used to wrap errors in useful info
- therefore instead of new Error() we should always be using errors.SomeError from @tryghost/error
- We should not require server or frontend files inside the shared libraries as these are intended to be required FROM the server and frontend components
- Now that we've resolved the two outstanding warnings, make this an error so we can't regress on this easily
- index.js files are meant to be an index, not contain behaviour or logic
- files longer than 50 lines are indicative of code in the wrong place, all though not definitive
- enabling this as a hint to get us to move code to better locations
- We want to keep behaviour in services and libraries, not in API endpoints
- This rule runs complexity _only_ on the query methods, and has it set super low - just 3
- Methods that have higher complexity are a great indicator of places where we've left behaviour in the API, however!
- It's indicative, not definitive. At least with an eslint rule we can if needs be disable it where we decide the code is OK
- These rules will help us to enforce that server code should not be required from the frontend, and vice versa
- They are disabled/off for now because they are too noisy and not quick to fix
- Having them in place makes it easy to set them to warn to preview how we're getting on with fixing them ahead of enabling them

- I wrote a custom plugin for the no-cross-requires logic between our modules after not finding anything that could do it
- Then, when searching for the next rule I wanted, I found eslint-plugin-ghost has no-restricted-requires
- This rule is more flexible, so switching to it
- NOTE: This update to eslint-plugin-ghost also fixes performance of linting our test files by pinning eslint-plugin-mocha to v7 as v8 has performance problems
- Using JS files to configure eslint gives us more power, e.g. being able to calculate paths
- We already use JS in pretty much every other repo we own, including admin... it's just Ghost we don't, and it's time!
