March 2025posted on 03.21.2025ESLint's no-restricted-syntax rule ESLint's no-restricted-syntax uses selectors to query an AST and this can be used to restrict certain syntax from being used. Use a AST Explorer to view the resulting AST of the JavaScript code you want to query. This rule disallows the use of MyLibrary.myFunction(): { "rules": { "no-restricted-syntax": [ "error", { "selector": "MemberExpression[property.name='myFunction'][object.name='MyLibrary']", "message": "'MyLibrary.myFunction()' is depreciated. Please use MyOtherLibrary.myNewFunction()" } ] } } This rule disallows the use of MyLibrary().myFunction(): { "rules": { "no-restricted-syntax": [ "error", { "selector": "[property.name='myFunction'] CallExpression[callee.name='MyLibrary']", "message": "'MyLibrary().myFunction()' is depreciated.
