Angular-cli : Using ng lint

Question

I'm aware the angular-cli uses codelyzer which uses lint.js

When using the command: ng lint

Can it automatically fix formatting? or will it only notify of formatting errors?

ng lint --help outputs all help commands for the angular-cli.

Answer 1

Updated answer for Angular CLI v6.x, 7.x, 8.x:

ng lint <project-name> --fix

where <project-name> is "name:" from package.json

-- answer for Angular CLI v1.x --

ng lint -fix

-- Original answer below --

To have tslint autofix many errors run the following in the root of your code. Obviously it can only autofix simpler issues like let -> const, "" -> ' etc.

npx tslint src/**/*.ts --fix 

Yesterday I did this to auto-fix hundreds of let -> const issues in our fairly large code bases. Just reviewing the changes before committing took long enough, manually fixing them all would have taken over a day.

For Angular 6.0+ you can run ng lint with autofix like so:

ng lint <project> --fix 

where <project> is the name you gave to your project when running ng new.
