Guards

To access the I18nContext inside your guards use the I18nContext.current() helper function.

src/test.guard.ts

import { CanActivate, ExecutionContext, Injectable } from '@nestjs/common';
import { Observable } from 'rxjs';
import { I18nContext } from '@softkit/i18n';

@Injectable()
export class TestGuard implements CanActivate {
  canActivate(
    context: ExecutionContext,
  ): boolean | Promise<boolean> | Observable<boolean> {
    const i18n = I18nContext.current();
    console.log('current language', i18n.lang);

    return true;
  }
}

warning

This only works when running in an http context! So it works with express, fastify and graphql (most parts).

Internally @softkit/i18n uses a middleware instead of an interceptor when running in an http context. To disable this behaviour set the disableMiddleware option to true.
