ngx-usage

ngx-usage

cli tool for analyzing usage of Angular components, pipes, directives, services

What it can do for me?

• list components most probably not used in your app
• list pipes, directives, serices most probably not used in your app
• list components, pipes and directives usage summary
• count usages of component/directive/pipe/service from given file in project
• count usages of any component by selector/class name, i.e. from third party library

How does it work?

Using ts-morph files from project (provided by tsconfig file) are parsed and usage stats are counted.

Component usages are checked in templates of other components from project and component's class reference in other files from project.

Component is considered unused when it's template is not used and class is referenced only in module (.module.ts) or test (.spec.ts) files.
