从另一个方法调用对象的方法

Question

I have some module file:

const dbModule = module.exports = {
  setBase: (apiKey, base) => new Airtable({ apiKey }).base(base),
  base: dbModule.setBase('', '')
}

But I get an error message during compile: variable 'dbModule' used before its declaration .

So how can I define base method to call setBase ?

Answer 1

Rather than declare the variable you are exporting as one step, you could separate it out into multiple steps:

const dbModule = {
  setBase: (apiKey, base) => ....
};

dbModule.base = dbModule.setBase('', '');

module.exports = dbModule;

Answer 2

I'm assuming you have defined dbModule elsewhere in your code.

class dbModule {

  setBase() {
  ....
  }
  base() {
    setBase();
  }
};
module.exports = new dbModule();

This class based programming makes sure that each of your functions belong to the class object and can access one another.
