How to fix process.nextTick is not a function with Calgolia places.js?

I hope this helps . Constants such as 'window' don't exist on a node.js app, as it's not situated within a viewport. Create a placeholder function like the following, to overcome the error:
code :
(window as any).process = {
   env: { DEBUG: undefined },
   nextTick: function() {
     return null;
   }
};

'process.nextTick(function() { throw err; })' - Undefined is not a function (mongodb/mongoose)

With these it helps From the provided information, it looks like you are using mongodb 2.0 driver. The db.collectionNames method was dropped. Check out the "Db Object" section of this page - https://github.com/mongodb/node-mongodb-native/blob/0642f18fd85037522acf2e7560148a8bc5429a8a/docs/content/tutorials/changes-from-1.0.md#L38
They've replaced it with listCollections. You should get the same effect with:
code :
mongoose.connection.db.listCollections().toArray(function(err, names) {
    if (err) {
        console.log(err);
    }
    else {
        names.forEach(function(e,i,a) {
            mongoose.connection.db.dropCollection(e.name);
            console.log("--->>", e.name);
        });
    }
});

process.nextTick is not a function (React native, ddp, meteor)

With these it helps process.nextTick doesn't exist on React Native so we've got to polyfill it. That is as simple as process.nextTick = setImmediate.
Example: https://github.com/spencercarli/meteor-todos-react-native/blob/master/ReactNativeTodos/app/config/db/lib/process.polyfill.js

Will enclosing the caller function and the called function inside process.nextTick make them asynchronous?

around this issue No. If the startPolling() function is blocking, then putting it in nextTick() callback won't help. It will block the entire thread on the next tick of the event loop - but it will block it nonetheless.
Example:
code :
function x() {
    fs.readFileSync('file');
}
x(); // <-- it blocks here
console.log('...');
function x() {
    pricess.nextTick(() => fs.readFileSync('file'));
}
x();
console.log('...');
// <-- it blocks here
// (end of file)

Node.js asynchronous function, process.nextTick()

I wish this help you If you have just CPU code (no I/O) you should try and go as far along as you can. Avoid async and tiny functions which fragment your code unnecessarily.
Take the opportunity and write clean, readable, linear code whenever possible. Only revert to async when absolutely necessary, such as stream I/O (file or network).
code :
function validateUser1(user, callback) {
   //validate user, some regex and stuff
   callback(err, user);
}

When does the callback function passed to process.nextTick() get processed?

around this issue I think that the documentation from that point after is quite explicative:
code :
let bar;

function someAsyncApiCall(callback) {
  process.nextTick(callback);
}

someAsyncApiCall(() => {
  console.log('bar', bar); // 1
});

bar = 1;
// << callback will execute here with bar being assigned
