🕗 Version & Regression Information
Give my project:
my-project/ ├─ src/ │ ├─ index.js ├─ tsconfig.json The following code:
import ts from 'typescript'; let tsConfigFile = ts.findConfigFile( process.cwd(), ts.sys.fileExists, "tsconfig.json" ); const { config } = ts.readConfigFile(tsConfigFile, ts.sys.readFile); const program = ts.createProgram(['src/index.js'], config); program.getSourceFiles().forEach((sf) => { console.log(1, sf.fileName); });Where tsconfig.json looks like:
{ "compilerOptions": { "strict": true, "outDir": "./dist-types", "target": "ESNext", "allowSyntheticDefaultImports": true, "moduleResolution": "NodeNext", "module": "NodeNext", "lib": ["ESNext", "DOM"], "declaration": true, "emitDeclarationOnly": true, "allowJs": true, "checkJs": true, "skipLibCheck": true, "verbatimModuleSyntax": true }, "include": [ "src/index.js" ], "exclude": ["node_modules"], }Outputs:

I feel like this did work in the past, or at least should work on regular js files as well.
