How to use gaurds on module level in nest.js? - module

Question

I want to use the gaurds on module level instead of controller routes and global module.
How can I do that?
I have this gaurd on my code:
#Injectable()
export class AuthGuard implements CanActivate {
constructor(private readonly verifyOptions?: VerifySessionOptions) {}
async canActivate(context: ExecutionContext): Promise<boolean> {
const ctx = context.switchToHttp();
let err = undefined;
const resp = ctx.getResponse();
await verifySession(this.verifyOptions)(ctx.getRequest(), resp, (res) => {
err = res;
});
if (resp.headersSent) {
throw new STError({
message: 'RESPONSE_SENT',
type: 'RESPONSE_SENT',
});
}
if (err) {
throw err;
}
return true;
}
}
I have many modules in my app like applications, chat, share etc and I want to protect the routes. For that protected routes I want to use this AuthGaurd.
But I don't want to use the gaurd on each and every controller endpoint like this:
#Post()
UseGaurds(new AuthGaurd())
async createApplication(
#Body() createAppData: CreateApplicationDto,
#Session() session: SessionContainer
) {
try {
const newDoc = await this.applicationService.create(createAppData);
return utils.sendSuccess(SUCCESS.S200.DEFAULT, newDoc);
} catch (error) {
throw new BadRequestException();
}
}
I want to use the gaurd on module level. Not on the global module but the modules like application, chat, share etc.
This is what my applicationModule looks like:
#Module({
imports: [SequelizeModule.forFeature([Application])],
providers: [ApplicationServices, ...applicationProvider, ...shareProvider],
exports: [ApplicationServices],
controllers: [ApplicationController],
})
export class ApplicationModule {}
