angular2, file should end with a newline, and trailing space

Question

I am new to angular2 and typescript, I got this 3 errors, I don't understand how to fix trailing whitespace and file should end with a newline.

Answer 1

The errors come from tslint which defines some rules on your project and check if your code matches the rules. You need to either fix the error or ignore/disable those rules.

file should end with a newline

You can ignore this rule on tslint.json by adding this on the rules object property

 "eofline": false

-

trailing whitespace

You can ignore this rule on tslint.json by adding this on the rules object property

 "no-trailing-whitespace": false

Answer 2

The error is coming from your code linter.

A code linter looks for code formatting inconsistencies and throws exceptions when you violate some rules (that you can specify manually).

This means it's a formatting error on your code. Your linter is basically telling you to add an empty line at the end of the file events/event-list.component.ts. Moreover, there is a trailing whitespace somewhere in that file. There are text editor tools that can do this built-in or with a plugin, and I suggest looking for that feature on your editor. If not, you can look for online tools that strip trailing whitespace on your code.
