CargoDB is a database which uses filesystem to store data in files (cargos). It provides really simple API and omits bullshit solutions that make your code even more complex.


First of all you must create the storage. Actually you can create as many storages as you want.

import Cargo  from 'cargodb'
const Cargo = require('cargodb')

const storage = new Cargo('my_storage')

You can also provide a path parameter which can point some other place in your directory (because right now it's initing in the root of your project)

const storage = new Cargo('my_storage','/absolute/path/to/create/storage')

// Path from root of the project
const storage = new Cargo('my_storage','~/path/to/dir/from/root')

Static Cargos 🚛

Trucks are basically what you would need for instance when writing an Electron app.

Trucks behave the same way as JavaScript's localStorage does. You can just get item and set item.

// Setting item
storage.set('key', 'value')

// Getting item
let result = storage.get('key')

Important note

Static cargo name (and collection names) shall match the following regular expression: /^[A-Za-z0-9@$\-#%&_()\[\]{}]+$/.

Cargo Collections 🚢

Cargo collections are really just collections of data. They behave similarly to the way for instance MongoDB does. These can store big number of cargos and they provide really convenient methods on manipulating the data.

You can create a collection (this just tells Cargo that such collection will be used).


Accessing collection can be done using in method'articles')

Let's put some cargo into our collection:

// Add a Cargo to the collection
// The method returns the newly 
// created cargo's ID'users').add({
    name: 'Joe',
    age: 20,
    dev: true

From now on we can basically do whatever we want with the data inside of the collections. Here are some usage examples:

const users ='users')

// Add new cargo file.
const id = users.add({
    name: 'Ann',
    age: 19,
    dev: false

// Get a cargo by ID.

// Find cargos by criteria.
// If function returns true,
// then the cargo fits the criteria.
// Get all users older or equal to 18.
users.find(user => {
    return user.age >= 18

// Overwrites the whole cargo
// with this new one.
users.set(id, {
    name: 'Anna',
    age: 20,
    happy: true

// Updates only the fields provided
// (undefined value removes the property).
users.update(id, {
    age: 21,
    happy: undefined,
    dev: true    

// Remove a cargo by ID.

Rusty Containers 🗝️

Rusty containers are basically files that are corrupted in some way. When cargo finds one it changes given file extension to .rusty.cargo. If you want to handle those situation, you can listen to a "rusty" event dispatched by cargo instance. Remember that listening to rusty event removes errors from the console.

storage.onRusty(path => {
    console.log(`My cargo file has been corrupted ${path}`)
    // Remove the file / Fix the file
