tsro/dist/modules/diagnostics.js

TypeScript Remove Orphaned (tsro) is a CLI utility and library for TypeScript projects that detects and removes files containing invalid imports — imports that refer to nonexistent entities or nonexistent modules.

import ts from "typescript";
import { validateImportsInFile } from "./imports.js";
export const collectDiagnostics = (params) => {
    const { fileNames, options = {}, ignoreLibImports } = params;
    const program = ts.createProgram(fileNames, options);
    const diagnostics = [];
    for (const file of fileNames) {
        const sourceFile = program.getSourceFile(file);
        if (!sourceFile) {
            throw new Error(`"${file}" not found`);
        }
        diagnostics.push(...validateImportsInFile(sourceFile, program, ignoreLibImports));
    }
    return diagnostics;
};
