Error Handling

Typetron automatically handles known errors for you. Every error in the app passes through the AppErrorHandler class found inside the Services directory. You can modify the existing AppErrorHandler inside the Services directory if you want a custom error output. The default error handler looks like this:

import { ErrorHandler, Request } from '@Typetron/Web'

export class AppErrorHandler extends ErrorHandler {

    handle(error: Error, request?: Request) {
        return super.handle(error, request)
    }
}

If you would like to handle errors differently for a production environment, you can do that like this:

import { ErrorHandler } from '@Typetron/Web'
import { Inject } from '@Typetron/Container'
import { AppConfig } from '@Typetron/Framework'

export class AppErrorHandler extends ErrorHandler {
    @Inject()
    appConfig: AppConfig

    handle(error: Error) {
        if (this.appConfig.environment === 'production') {
            // something different
        }
        return super.handle(error)
    }
}
