Angular-meteor tutorials have a method known as '/parties/insert' that is already clearly defined and explained

I am currently diving into meteor + angular and enjoying learning through !

As I was working on the 3-way data binding section, I created a folder named collections within the socially folder. In this folder, I made a file called parties.ts where I added the following two lines of code:

import {Mongo} from 'meteor/mongo';
export let Parties = new Mongo.Collection('parties');

However, I encountered an error message while doing so. Below is the error log that was generated:

C:\<user>\AppData\Local\.meteor\packages\meteor-tool\1.3.2_4\mt-os.windows.x86_32\dev_bundle\server-lib\node_modules\fibers\future.js:245
                    throw(ex);

I would greatly appreciate any assistance or advice from the community regarding this issue. Thank you in advance!

Answer №1

I encountered a similar issue and managed to resolve it successfully. I was utilizing Atom along with the Atom TypeScript plugin, which was automatically converting TypeScript files to JavaScript independently from Meteor, resulting in unnecessary files being created.

Below are the steps I followed to rectify the situation:

  1. Review your tsconfig.json file to ensure that it contains these lines (modify or add them if needed):

    "buildOnSave": false,
    "compileOnSave": false,

  2. Close and reopen Atom to ensure that the Atom TypeScript plugin adopts the new settings and halts the automatic conversion of TypeScript to JavaScript on save.

  3. Delete all *.js and *.map files within your "client", "server", and "both" directories.

  4. If your Meteor instance is currently running, halt it by using "ctrl-c" or "command-c", depending on your OS.

  5. Execute "meteor reset" in the command line.

  6. Run "meteor" in the command line to recompile your TypeScript files and restart Meteor.

Following these steps, everything functioned correctly for me.

Answer №2

If you're encountering issues, it could be due to TypeScript not compiling properly into JavaScript. One solution is to delete the JS file in the folder, make edits to your TypeScript file, and save it. After recompiling, the error should be resolved.

Answer №3

Hey there, I encountered a similar error. Have you managed to find a solution for it?

After some troubleshooting, I was able to resolve the problem by including "compileOnSave": false" in my tsconfig file. I typically use Atom as my editor, and it was automatically compiling the code.
