node-red-contrib-objectid

Node-Red Node to create an ObjectID for queries in mongodb

Forking Note

I will publish this fork under the name of node-red-contrib-bson until the contributors in node-red-contrib-objectid treats message properly with RED.util.getMessageProperty and RED.util.setMessageProperty.

Usage

This small node-red node is used to create an ObjectID for mongodb.

The selected property in msg will be converted to an ObjectID, you can input a 24 char hexstring and create an ObjectID from it.

For example: msg._id = "572dbc06f307c8682045c55c"

If the target property is null, a random id is created.

Deep reference

Deep reference is supported as a dot-separated string, e.g. payload._id.

Array support

This module provides limited array support when the ending value is array.

For example, the following will work via this path "payload._id.$in":

{
  payload: {
    _id: {
      $in: [
        "5a8a92939034785a569ae7b8",
        "5a8a92979034785a569ae7b9"
      ]
    }
  }
};
