mondex

CLI tool to create and manage MongoDB indexes

Installation

Install the package globally or alternatively you can also use npx

npm install -g mondex

Usage

Here is the list of mondex commands that you can use

• pull — creates index configuration file by pulling existing indexes from your database
• plan — shows the indexes to be created or dropped
• apply — applies the changes from the configuration file (i.e. apply or drop indexes)

The list of options accepted by mondex are

Usage: mondex <command> [options]

Commands:
  pull                       Creates index configuration from database
  plan                       Shows the index changes to be applied to database
  apply                      Applies the index changes from configuration to database

Options:
  -V, --version              output the version number
  -h, --help                 display help for command

  -f, --file <file>          path to indexes file (defaults to indexes.json in current directory)
  -i --uri <uri>             connection string for MongoDB
  -d, --db <database>  database name

Configuration

The index configuration file is an array of objects with each object having two properties:

• collection: Name of the collection
• indexes: Array of indexes to be created

Index format is same as the one you would pass to db.collection.createIndex() in the mongo shell.

Given below is a sample JSON file representing sample index configuration:

[
  {
    "collection": "user_resource_progress",
    "indexes": [
      { "resourceId": -1, "resourceType": -1, "userId": -1 },
      { "deletedAt": -1, "createdAt": -1 }
    ]
  },
  {
    "collection": "user",
    "indexes": [
      { "email": -1 },
      { "userType": -1, "createdAt": -1 },
      { "organizationId": -1, "userId": -1, "isActive": -1 }
    ]
  }
]

Once you have the JSON file ready, you can use the mondex to start managing your indexes.

Examples

Show the indexes that will be created and dropped

mondex plan --uri mongodb://localhost:27017 --db mydb --file ./indexes.json

Apply the changes from index configuration

mondex apply --uri mongodb://localhost:27017 --db mydb --file ./indexes.json

Pull existing database indexes in the configuration file

mondex  pull --uri mongodb://localhost:27017 --db mydb --file ./indexes.json
