Disallow usage of restricted global variables in community nodes (@n8n/community-nodes/no-restricted-globals)

💼 This rule is enabled in the ✅ recommended config.

Rule Details

Prevents the use of Node.js global variables that are not allowed in n8n Cloud. While these globals may be available in self-hosted environments, they are restricted on n8n Cloud for security and stability reasons.

Restricted globals include: clearInterval, clearTimeout, global, globalThis, process, setInterval, setTimeout, setImmediate, clearImmediate, __dirname, __filename.

Examples

❌ Incorrect

  async execute(this: IExecuteFunctions) {
    // These globals are not allowed on n8n Cloud
    const pid = process.pid;
    const dir = __dirname;

    setTimeout(() => {
      console.log('This will not work on n8n Cloud');
    }, 1000);

    return this.prepareOutputData([]);
  }
}

✅ Correct

  async execute(this: IExecuteFunctions) {
    // Use n8n context methods instead
    const timezone = this.getTimezone();

    return this.prepareOutputData([]);
  }
}
