tsconfig.json is ignored

Hi everyone, I’ve just realized that tsconfig.json is being ignored. How can I tell to esbuild that we have a tsconfig file?

Assuming you did require('./tsconfig.json'), then your error is because you’re using Node.js’s require to import a JSON with comments. Official JSON spec doesn’t support comments.

Typescript has a custom JSON parser that supports comments. For your use-case, you can use strip-json-comments or json5:

JSON.parse(stripJsonComments(fs.readFileSync('./tsconfig.json')));

JSON5.parse(fs.readFileSync('./tsconfig.json'));

You can also read the raw tsconfig.json file with the building Typescript config reader API:

function getRawTSConfig(filename: string): any {
  return ts.readConfigFile(filename, fn => fs.readFileSync(fn).toString()).config;
}
