baldrick-tsconfig-es2020 v0.9.0

baldrick-tsconfig-es2020

Shared basic TypeScript config for ES2020

This is not an official base. It should support Node.js 14 and above, but should provide ES2020 support for ES modules.

It includes:

• strict is activated (true) and enables a wide range of type checking behavior that results in stronger guarantees of program correctness.
• esModuleInterop is activated (true) which should result in better support for import of dependencies regardless whether they are ES or commonjs.
• skipLibCheck is activated (true) and skip type checking of declaration files.
• forceConsistentCasingInFileNames is activated (true) and TypeScript will issue an error if a program tries to include a file by a casing different from the casing on disk.
• declaration is activated (true) and generate .d.ts files for every TypeScript or JavaScript file inside your project.
• newLine is set to LF (unix).
• noImplicitReturns is activated (true) and TypeScript will check all code paths in a function to ensure they return a value.
• noImplicitOverride is activated (true) and you can ensure that the sub-classes never go out of sync, by ensuring that functions which override include the keyword override.
• noUnusedLocals is activated (true) and you get report errors on unused local variables.
• noUnusedParameters is activated (true) and you get report errors on unused parameters in functions.
• noFallthroughCasesInSwitch is activated (true) and you get report errors for fallthrough cases in switch statements.
• noUncheckedIndexedAccess is activated (true) and this will add undefined to any un-declared field in the type.
• noPropertyAccessFromIndexSignature is activated (true) and will raise an error when the unknown field uses dot syntax instead of indexed syntax.
• noEmitOnError is activated (true) and this will not emit compiler output files like JavaScript source code, source-maps or declarations if any errors were reported.
• useDefineForClassFields is activated (true) and switches to the upcoming standard version of class fields runtime behavior.
