Arango Migration Tool

This tool will help you to manage your ArangoDB with migration file to easily create users, document, indexes & views from a simple folder with yaml files.

It can also insert default data from the same folder.

Getting started

1. Installation

# install localy, so you can use it with npx in your folder
npm install arangomigration

# or install globaly to get access to the cli from anywhere
npm install -g arangomigration

2. Add some migration files

• Create a migration folder at your project root
• Add yaml files in semvers format with a name: x.x.x-add-a-collection.yml

Your folder should look like this:

./migration
├── 1.0.0-mvp-needs.yml
└── 1.0.1-add-missing-index.yml

3. Write a migration file

database: my-database

create:
  users:
    - username: user1
      password: usernamepassword
  collection:
    - name: dogs
    - name: dogSitter
  edgeCollection:
    - name: dogSitterDogs
  indexes:
    - name: oneDogSitterForADog
      collection: dogSitterDogs
      type: persistent
      unique: true
      fields:
        - _from
        - _to

This migration file will do:

• Create my-database database if not exist
• Create user1 user in _system database
• Create a collection and an edge collection
• Create a persistent index on the edgeCollection dogSitterDogs to ensure that a dog has only a dog sitter
