# Global Dependencies { #global-dependencies }

For some types of applications you might want to add dependencies to the whole application.

Similar to the way you can [add `dependencies` to the *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, you can add them to the `FastAPI` application.

In that case, they will be applied to all the *path operations* in the application:

                    messages.addErrorsFailedToStartJob(GLOBAL, entity.getName());
                });
            }
            try {
                entity.start();
            } catch (final Exception e) {
                throwValidationErrorApi(messages -> {
                    messages.addErrorsFailedToStartJob(GLOBAL, entity.getName());
                });
            }
        }).orElse(() -> {

        try {
            userService.store(entity);
            saveInfo(messages -> messages.addSuccessCrudCreateCrudTable(GLOBAL));
        } catch (final Exception e) {
