Getting Started with Space Cloud

Follow this guide to get started using space-cloud in a project from scratch.

Note: If you instead want to play around with space-cloud to see what it can do, then check out the Quick start.

Since space-cloud bridges the gap between your frontend and database, it involves a 3-tier architecture as shown below:

Basic Space Cloud architecture

Thus, using space-cloud in a project requires you to configure three parts:

  • Database (Prerequisite)
  • Space Cloud
  • Frontend

Step 1: Start your Database

space-cloud exposes realtime CRUD functionalities over any database of your choice. In order for that to work, you first need to have your database up and running. space-cloud supports the following databases as of now:

  • Mongo DB
  • MySQL and MySQL compatible databases (For eg. TiDB)
  • Postgres and Postgres compatible databases (For eg. CockroachDB, Yugabyte etc.)

Step 2: Download Space Cloud

Once you have your database up and running, you need to make sure that you have the latest version of the space-cloud binary on your machine. This binary is the server connecting to your database and creating the endpoints for it. You need to download a binary for your operating system or you could build it directly from its source code. You will need go version 1.11.2 or later to build it from the source.

Download the binary for your OS from here:

You can unzip the compressed archive

For Linux / Mac: unzip

For Windows: Right click on the archive and select extract here.

Make the space-cloud binary executable and add it to your path.

For Linux / Mac: chmod +x space-cloud

Step 3: Configure Space Cloud

Space Cloud needs a config file in order to function. The config file is used to load information like the database to be used, its connection string, security rules, etc.

You can use a sample config file from here here.

Or else you can create a bare minimum config file for a project using the following command from the folder containing space-cloud:

For Linux / Mac: ./space-cloud init

For Windows: space-cloud.exe init

This is how the config file looks like.

id: space-cloud
secret: some-secret
      conn: mongodb://localhost:27017
      isPrimary: true
          isRealtimeEnabled: true
              rule: allow
              rule: allow
              rule: allow
              rule: allow
      enabled: true
    enabled: false
    nats: nats://localhost:4222
    enabled: true
    kafka: localhost
    enabled: false
    storeType: local
    conn: ./
        prefix: /
            rule: allow
            rule: allow
            rule: allow

Quickly going through it, id is the project name. secret is the secret key used for signing and parsing JWT tokens. All the configuration for individual modules goes under the modules key. Currently, crud, auth (user management), functions (functions), realtime and fileStore are supported.

Note: The in-depth configurations of various modules are explained in their corresponding sections.

Step 4: Start Space Cloud

You can start space-cloud with the following command.

For Linux / Mac: ./space-cloud run --config config.yaml

For Windows: space-cloud.exe run --config config.yaml

Next steps

As you have both the database and the space-cloud up and running, the next task is to set up your frontend app to use space-cloud and start building an app! Check out the language specific guides below to help you do this:

  • Javascript for web and Nodejs projects.
  • Java for Android and Java projects. (coming soon)
  • Python for Python projects.
