Issue with consumer about redis-smq HOT 6 CLOSED

Please provide more information about your environment. Are you using babel or running nodejs with --experimental-modules flag?

It seems that you are having a problem with ES6 modules and commonjs which is used by this packages (module.exports/require). This issue seems not to be related with the package itself.

I believe that mixing ES6 modules with commonjs does not work and it should be avoided.

Have you tried to use module.exports/require instead of import/export?

I mean this way:

const { Consumer } = require('redis-smq');

/**
 * Consumer manager
 */
module.exports = class ConsumerQueueManager extends Consumer {
  constructor() {
    super();
  }

  /**
   * @param {Message} message
   * @param {function} cb
   */
  consume(message, cb) {
    console.debug(message);
    cb();
  }
}

Then in you application kernel import ConsumerQueueManager like:

const ConsumerQueueManager = require('./consumer-path');
...

I already tried and same problem.
I´m using node v10.3.0
I´m using babel to transpile the project and I´m trying babel-watch to develop locally and I have the same issue.

With babel watch: babel-watch --watch lib --watch config -- ./lib/index.js
With babel transpiler: babel lib -d dist -D

from redis-smq.

I am convinced that this issue is related to babel and the way it transpiles the code.

Unfortunately I do not provide any assistance with babel issues as they are not related to this project.

I suggest you inspect the transpiled code. Google can be your best friend.

This package has been tested on node v10.3.0 and all tests passed successfully.

@weyoss You were totally right. If somebody is using babel needs to exclude class transform:

That example is for babel7

"presets": [
      ["@babel/preset-env", { "exclude": ["transform-classes"] }]
    ],

Glad you got it fixed!
