Use collection insert inside meteor method (server side)

Check this thread:

Mongo only inserts first object inside promise, how to see error?

hi, I have a method, and this uses a promise to get external data (this works perfectly). The first database insert works fine (for testing purposes) but if I do it inside the loop of my promise he only inserts the first. And I suspect an error but how can I see the error? if I remove the mondoDB Apps.insert statement it prints the name of all my objects… so it goes wrong here thank you! updateAppsCollection(){ console.log('Method: update the local mongoDB with fresh data from Qlik S…

That conversation continued over several PMs. The conclusion was that Meteor’s inbuilt Promises work as expected with fibers/futures, but other Promise libraries don’t play well. If you really cannot use Meteor’s Promises, your best bet will be to use the standard npm module methods (without callbacks) which Meteor uses under the hood: these return Promises. So, instead of doing a normal Meteor insert like this:

function sendDB (frenchArray) {
  ...
  Tags.insert(...);

you would do something like

async function sendDB (frenchArray) {
  ...
  const idTag = await Tags.rawCollection().insert(...);

or use a standard doThing().then(doOtherThing) promise chain.

You should then be able to use Q (never tried Q, but I was able to get Bluebird to work this way). Note that the syntax of these methods is not quite the same as the exposed Meteor methods. Check the docs for more information
