✅ Viability Checklist

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This isn't a request to add a new utility type: https://github.com/microsoft/TypeScript/wiki/No-New-Utility-Types

⭐ Suggestion

Just wanted to draw your attention that the ts.server.protocol.CompilerOptions interface is missing recently added properties that are present in ts.CompilerOptions. Like allowImportingTsExtensions, resolvePackageJsonExports, resolvePackageJsonImports, allowArbitraryExtensions , etc. Probably there are more:

TypeScript/src/server/protocol.ts

Lines 3665 to 3670 in 8c34b56

	export interface CompilerOptions {
	allowJs?: boolean;
	allowSyntheticDefaultImports?: boolean;
	allowUnreachableCode?: boolean;
	allowUnusedLabels?: boolean;
	alwaysStrict?: boolean;

TypeScript/src/server/protocol.ts

Lines 3713 to 3720 in 8c34b56

	preserveSymlinks?: boolean;
	project?: string;
	reactNamespace?: string;
	removeComments?: boolean;
	references?: ProjectReference[];
	rootDir?: string;
	rootDirs?: string[];
	skipLibCheck?: boolean;

@andrewbranch Could you take a look, please? Perhaps it is worth adding these too?

💻 Use Cases

Index signature covers them all. So this is not a problem. Only felt like those should be explicitly defined.

By the way, deprecated options like suppressExcessPropertyErrors, suppressImplicitAnyIndexErrors most probably have to be removed from ts.server.protocol.CompilerOptions in TypeScript 5.5.

TypeScript/src/server/protocol.ts

Lines 3724 to 3729 in 8c34b56

	strict?: boolean;
	strictNullChecks?: boolean;
	suppressExcessPropertyErrors?: boolean;
	suppressImplicitAnyIndexErrors?: boolean;
	useDefineForClassFields?: boolean;
	target?: ScriptTarget | ts.ScriptTarget;
