Express and Typescript - Error.stack and Error.status properties do not exist
Extend global Error
You can tell TypeScript that for your use case Error might have a status on it:
interface Error { status?: number;}So you get:
interface Error { status?: number;}var err = new Error('Not Found');err.status = 404;Alternative
Put the status on the res and send the err. For Example:
// catch 404 and forward to error handlerapp.use(function (req, res, next) { var err = new Error('Not Found'); res.status(404); // using response here next(err);});
The best way in my opinion, is not to disable type checks by setting the error to any, or creating a new Error type, since one already exists in @types/node.
Instead, you should extend that error type:
interface ResponseError extends Error { status?: number;}
You put the error code on the response...
app.use(function (req, res, next) { var err = new Error('Not Found'); res.status(404) next(err);});
