Error handling — Lanjit Docs

Register an exception renderer through withExceptions() in bootstrap/app.js. Use HttpException for errors whose status and message may be returned to clients. Keep APP_DEBUG=false in production so internal exceptions become a generic 500 response, and log failures without recording secrets.

Examples

import { HttpException } from '../framework/Foundation/Exceptions/HttpException.js';

throw new HttpException(404, 'Post tidak ditemukan.');

.withExceptions((exceptions) => {
  exceptions.render((error, request, response) => response.json({
    message: error.status && error.status < 500
      ? error.message
      : (process.env.APP_DEBUG === 'true' ? error.message : 'Server Error'),
    ...(error.details ? { errors: error.details } : {}),
  }, error.status ?? 500));
})

exceptions.render(async (error, request, response) => {
  await app.make('log').error(error.message, {
    method: request.method,
    path: request.path,
  });

  return response.json({ message: 'Server Error' }, error.status ?? 500);
});
