well, you can define the very last middleware using plain express middleware, like so
expressApp.use(
(
err: Error,
req: express.Request,
res: express.Response,
next: express.NextFunction
) => {
res.status(err.status || 500).json(error);
}
);

I would like to use a decorator to achieve similar functionality :)
from node-decorators.
So, I've implemented possible option for handling errors, due to added @decorators/di
support in @decorators/express
package, there's new possible option of handling errors:
import { ErrorMiddleware, ERROR_MIDDLEWARE } from '@decorators/express';
@Injectable()
class ServerErrorMiddleware implements ErrorMiddleware {
public use(error: Error, request: Request, response: Response, next: NextFunction) {
next();
}
}
Container.provide([
{ provide: ERROR_MIDDLEWARE, useClass: ServerErrorMiddleware }
]);
from node-decorators.
@serhiisol , what is Container
in example above?
from node-decorators.
@vasergen that's the container class from @decorators/di
package
from node-decorators.
@serhiisol , thanks
from node-decorators.
No problem
from node-decorators.
@serhiisol how do i wire this to my express app? I created:
import { ErrorMiddleware, ERROR_MIDDLEWARE } from '@decorators/express';
import { Container, Injectable } from '@decorators/di';
import { NextFunction, Request, Response } from 'express';
@Injectable()
class ServerErrorMiddleware implements ErrorMiddleware {
public use(error: Error, request: Request, response: Response, next: NextFunction) {
response.render('errorTemplate', { error });
}
}
Container.provide([{ provide: ERROR_MIDDLEWARE, useClass: ServerErrorMiddleware }]);
my express server setup currently looks like this:
server.use(compression());
server.use(logger('combined'));
server.use(express.json());
server.use(express.urlencoded({ extended: true }));
applySession(server);
applyView(server);
applyAuth(server);
attachControllers(server, [PollsController, AuthController, IndexController]);
from node-decorators.
@angelxmoreno looks good to me. What's the issue you're having?
