A lightweight Gitlab based JSON database with Mongo-style API. Backed by gitbreaker and mingo.

npm i gitlab-db

import GitlabDB from 'gitlab-db'

// Instantiate a database
const db = new GitlabDB('apple', {
  url: 'http://gitlab.example.com',
  token: 'your_access_token',
  repo: 'group/repo',
})

// Create a collection
db.createCollection('product')

// CRUD
db.collection('product').save({ name: 'iphone', v: '8', price: 699 })
db.collection('product').find({ name: 'iphone' })
db.collection('product').update({ name: 'iphone', v: '8' }, { price: 599 })
db.collection('product').remove({ name: 'iphone', v: '7' })

Repository structure will be:

└── <repository root>
    ├── apple
    │   └── product.json

Note: As all APIs returns a promise. I highly recommend the async/await statement like the following:

const result = await db.collection('product').save({ name: 'iphone', v: '8', price: 699 })

Instantiate a database.

• dbName: String Name of the database you want to create.
• options: Object
  • url: String Specify gitlab url, eg: http://gitlab.example.com.
  • token: String Specify your personal access token.
  • repo: String Specify repository name and group belongs to, format: group/repo.
  • branch: String Optional, specify branch, default: main.
• customGitlabAPI: Constructor Specify your custom GitlabAPI like @gitbeaker/browser.

Create a collection.

• collectionName: String Name of the collection you want to create.
• documents: Array Optional. Specifies default data of the collection about to be created.

Connect to a collection.

• collectionName: String Name of the collection you want to connect.
• options: Object Optional settings.
  • key: String Specify a key of the collection.

Inserts a new document(or multiple documents). This method will returns the inserted document(s).

• document: Object | Array A document or multiple documents to save to the collection.

Returns like:

Insert single document:

{ added: 1, document: {...} }

Insert multiple documents:

{ added: 2, documents: [{...}, {...}] }

Note: it will return { added: 0 } if a key is specified and the document that the key points to already exists.

Selects documents in a collection.

• query: Object Optional. Specifies selection filter using query operators. To return all documents in a collection, omit this parameter or pass an empty document ({}).

Returns like:

[{ _id: 1, ... }]

Modifies an existing document or documents in a collection.

• query: Object The selection criteria for the update. The same query selectors as in the find() method are available.
• update: Object The modifications to apply.

Returns like:

{ updated: 2 }

Another usage, execute multiple updates at once to reduce gitlab requests:

db.collection(collectionName).update([
    { query: { id: 1 }, update: { v: 1 } },
    { query: { id: 2 }, update: { v: 2 } },
])

Removes documents from a collection.

• query: Object Specifies deletion criteria using query operators.

Returns like:

{ removed: 1 }

Check if a collection exists.

• collectionName: String Name of the collection you want to check.

Returns like:

true

import { Gitlab } from '@gitbeaker/browser'; 
import GitlabDB from 'gitlab-db'

// Instantiate a database
const db = new GitlabDB('apple', {
  url: 'http://gitlab.example.com',
  token: 'your_access_token',
  repo: 'group/repo',
}, Gitlab)

// ETC...

• model check
• collection deletion
