How can I disable Cron by env?

are you talking about the @nestjs/schedule package?

if yes, either you can write a decorator that wraps the Cron decorator exposed by the @nestjs/schedule package
and use the applyDecorators from the @nestjs/common to conditionally apply it based on the environment variable.

or you can write the environment check logic inside the handler method.

I recommend the first approach; here's a sample:

// decorators/conditional-cron.decorator.ts

import { applyDecorators } from '@nestjs/common';
import { Cron, CronExpression } from '@nestjs/schedule';

export ConditionalCron = (envKey: string, expression: CronExpression) => {
  if (process.env[envKey] == 'true') {
    return applyDecorators(Cron(expression));
  }

  return applyDecorators(
    // apply something else...
  );
}


// X.service.ts
import { Injectable } from '@nestjs/common';
import { ConditionalCron } from './decorators/conditional-cron.decorator';

@Injectable()
export class XService {
  @ConditionalCron('ENABLE_X_CRON', CronExpression.EVERY_5_SECONDS)
  async handleCron() {
    // ...
  }
}

# .env
ENABLE_X_CRON=true

But is there a way to fully disable it on local , from the CronExpression enum i dont see that enum value
