How to wait for the end of the function-CodePudding

I have some task. I'm creating my library which has a connection function written in it (several processes are included) and a creation function. Need to clarify. The library doesn't deal with any http/https requests. Everything happens locally and without server requests.

Code from the testing side of the library

module.exports = async function connect(argument) {
    const { save, models } = argument;

    var prom = new Promise((resolve, reject) => {
        setTimeout(() => {
            checkDir(models);

            // check models
            checkBaseModels(models);
            checkModels(models);

            resolve();
        });
    });

    prom.then(() => {
        return new Promise((resolve, reject) => {
            setTimeout(() => {
                loadModels();

                resolve();
            }, 2000);
        });
    }).then(() => {
        setTimeout(() => {
            saveModels(save);
            models_list();
        });
    });
};

const cloud = require('cloud');

const cloud = cloud.connect({ save: 1000 });

const create = cloud.create({
    name: "Test",
    description: "Abc"
});

What can be used to make other processes stop while the connection in my library is running.

I need to somehow fix this problem without using setTimeout and so on in the test. It is desirable to leave this code as it is.

I need to connect first, and then create. The code on the test side, if possible, should preferably not be edited.

CodePudding user response：

connect function is not returning the promise

module.exports.connect = async function connect(argument) {
  //  ...
  return prom;
}

Connection file

(async () => {
  const cloud = await cloud.connect({ save: 1000 });
  const create = cloud.create({
    name: "Test",
    description: "Abc",
  });
})();

Код метода connect:

module.exports = async function connect(argument) {
    const { save, models } = argument;

    var prom = new Promise((resolve, reject) => {
        setTimeout(() => {
            checkDir(models);

            // check models
            checkBaseModels(models);
            checkModels(models);

            resolve();
        });
    });

    prom.then(() => {
        return new Promise((resolve, reject) => {
            setTimeout(() => {
                loadModels();

                resolve();
            }, 2000);
        });
    }).then(() => {
        setTimeout(() => {
            saveModels(save);
            models_list();
        });
    });
};

In create, for now, the function is simply set to.
