Why Eslint Throws No Unused Vars For Typescript Interface Stack To solve this issue in a pure typescript project, i added the following rule to my eslint config file (.eslintrc.json). for this particular solution to work, you must follow the convention that interface names begin with an upper case "i". Blocking builds on unused variables can be inconvenient. we generally recommend using @typescript eslint no unused vars to flag unused locals and parameters instead of typescript.

Eslint No Unused Vars Ignore Prefix Johnnyreilly Identifies and flags variables, parameters, and imported members that are declared but never used within your javascript code. if it finds any such unused elements, it generates a warning or error message, depending on your eslint configuration. To automatically remove unused imports, we will need to add the eslint plugin unused imports plugin. now, when you run eslint, you should see error lines saying error '' is defined but never used unused imports no unused imports for the files where you have unused imports. Variables that are declared and not used anywhere in the code are most likely an error due to incomplete refactoring. such variables take up space in the code and can lead to confusion by readers. this rule is aimed at eliminating unused variables, functions, and function parameters. Declaration merging an interface into a class is bad practice because it causes ts to create unchecked properties methods on that class. in the provided example it's "safe" because the method is explicitly marked as optional.

That's too bad about no undef and no unused vars. vscode does show those but not in the easy to spot way of eslint. but false errors are worse so i'll go ahead and use them, thanks. Learn how to use eslint to enforce no unused variables in your typescript code. this guide will help you write cleaner, more maintainable code that is less likely to contain errors. Typescript itself doesn't even catch this case in its nounusedparameters implementation. technically it's valid to omit the parameter you can omit arguments from an abstract interface method, but you cannot add non optional arguments. How to disable warn about some unused params, but keep "@typescript eslint no unused vars" rule. in your example, we see only the type promise, which doesn't mean that you are using user in your method, but only to define a type. eslint is expected : async mymethod(user: string): promise { some code with user parameter.
