Problem: Your dev team makes spelling mistakes in code
Problem: Your dev team makes spelling mistakes in code.
Solution: CSpell
CSpell has a command line interface. So, run it against your entire codebase on your CI server, or via precommit/prepush hooks.
Add words to the dictionary by creating cspell.json in your project root.

Oh, and if you're using VS Code, you can see real-time line spelling errors via Code Spell Checker: https://marketplace.visualstudio.com/items?itemName=streetsidesoftware.code-spell-checker

You might think "Does spelling matter?"
Absolutely. It slows reading, and is often a sign of a bug.
Example: I'm auditing a project that has dozens of spelling errors. CSpell helped me find a few bugs related to URL search params with typos in them.
Update: I just used CSpell to resolve over 1000 spelling issues in a large codebase. It found many user-facing spelling issues, as well as 100's of misspelled comments, functions, types, and variables.
Now we can run CSpell via CI so we can protect ourselves from future typos!
