I need to Add multiple language support for my Angular 4 Application.I need to know the best approach to achieve this.
You can use ngx-translate library that I used it and it is very useful for internationalization for Angular.Also I advice you about Angular, you should check jhipster project and then you can learn more advance and detail topics about Angular 4 and Spring Boot.It is very useful project and also you can create Angular and Spring Boot project rapidly...
