Earlier in this newsletter, we covered how to handle errors with RxJs Observables<\/a>. What about errors in the rest of the application? Javascript has a primary try\/catch mechanism<\/a>, but this doesn’t help handle errors in a generic, unified way.<\/p>\n\n\n\n

Fortunately enough, Angular has an ErrorHandler<\/code><\/a> interface that can be implemented by global error handler services such as this one:<\/p>\n\n\n

\"\"<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n

That way, we can implement a catch-all method to deal with errors and display them to the user consistently (code example here). Even better, such a service could report errors to a server for further investigation and debugging from the dev team.<\/p>\n\n\n\n
