Database as a service

Database without the management, backup and scaling.

Quick links:

At its core, StaticBackend’s primary offering is a database as a service allowing you to perform CRUD operations. Here’s how to manage your user’s data.

Indexed per account by default

Each repository (collection, “table”) you’ll create will always have an accountId field, which is an index for performance reasons and security.

This accountId is automatically set for you from the authenticated user’s information.

Public repository

Sometimes you need repositories that can be read by all your users. Editing and deleting a record is only allowed for the record owner.

Prefixing the name of the repository with pub_ will turn a repository as public. Note that users are not required to be authenticated to read public repositories.

Use public repositories only in scenario where you need to display data to users that are not signed up yet.

Permissions

We’ve borrowed the same permission concept as Unix, where you have three levels of permissions:

The owner, the account, and everyone else.

Each permission level has three access possible.

Read, write, and execute.

We use an octal value to define the permissions. For instance, giving full permission to the owner, reading permission to the account, and no permission for everyone else defines as 740.

For full access to owner, read and write access to account and read access for everyone: 764.

Read access is 4. Write access is 2 and execute access is 1. You add all needed access together to form the right octal value.

You can tag your repositories with specifics permissions by using the suffix _perm_. For instance, posts_764_.

The default permissions are 740 so you don’t need to specify that one. Note that everyone else means authenticated users. To allow non-authenticated users the read access, you must use the pub_ prefix.

Make sure you plan ahead and choose your permissions carefully as they cannot be changed at this moment. Once a repository is created you cannot change its permissions.

Operations on behalf of your users

Pieces of your application will need to impersonate users to perform database operations. Think, for instance, of a daily job that processes your trial expiration. You might want to remove data on behalf of the expire user.

Due to this, we have introduced Sudo actions that can only be called from a server-side environment. For example, the following database operations can be executed from a specific route using the ROOT_TOKEN authentication. Refer to the root token page for more detail.

Create a document

Adds a document to a repository.

HTTP request:

POST /db/{repository-name}

Format: JSON

Body:

Your JSON will be stored as-is with the addition of an id and accountId fields.

Example:

curl -H "Content-Type: application/json" \
     -H "SB-PUBLIC-KEY: your-pub-key" \
     -H "Authorization: Bearer user-token" \
     -X POST \
     -d '{"name": "task name", "done": false}' \
     https://na1.staticbackend.com/db/tasks

const doc = {
  name: "task name",
  done: false
}
const result = await bkn.create(session_token, "tasks", doc);
if (!result.ok) {
  console.error(result.content);
  return;
}
console.log(result.content);

task := Task{
  Name: "task name",
  Done: false,
}

err := backend.Create(token, "tasks", task, &task)

Response:

{
  "accountId":"5e184d95b1374eaf8b994bf3",
  "done":false,
  "id":"5e185aceb1374eaf8b994bf6",
  "name":"task name"
}

Create documents in bulk

Adds multiple documents to a repository.

This is recommended vs. looping and calling the single create document endpoint.

HTTP request:

POST /db/{repository-name}?bulk=1

Format: JSON

Body:

An array of documents.

Example:

curl -H "Content-Type: application/json" \
     -H "SB-PUBLIC-KEY: your-pub-key" \
     -H "Authorization: Bearer user-token" \
     -X POST \
     -d '[{"name": "task 1", "done": false}, {"name": "task 2", "done": true}]' \
     https://na1.staticbackend.com/db/tasks?bulk=1

const docs = [{
  name: "task 1",
  done: false
}, {
  name: "task 2",
  done: true
}];
const result = await bkn.createBulk(session_token, "tasks", docs);
if (!result.ok) {
  console.error(result.content);
  return;
}
// true or false
console.log(result.content);

tasks := []Task{Task{
  Name: "task 1",
  Done: false,
},
Task{
  Name: "task 2",
  Done: true,
}}

ok, err := backend.CreateBulk(token, "tasks", tasks)

Response:

true

List documents

List documents for a repository.

HTTP request:

GET /db/{repository-name}

Querystring parameters:

name type description
page number Result page (starting at 1, default to 1)
size number How many document per page (maximum 100, default to 25)

Example:

curl -H "Content-Type: application/json" \
     -H "SB-PUBLIC-KEY: your-pub-key" \
     -H "Authorization: Bearer user-token" \
     https://na1.staticbackend.com/db/tasks?size=2&desc=true

const optionalParams = {
  page: 1,
  size: 2,
  descending: true
}
const result = await bkn.list(session_token, "tasks", optionalParams);
if (!result.ok) {
  console.error(result.content);
  return;
}
console.log(result.content);

params := &backend.ListParams{
  Page: 1,
  Size: 20,
  Descending: true,
}

var tasks []Task
result, err := backend.List(token, "tasks", &tasks, params)
fmt.Println("tasks hold the result", tasks)

Response:

{
  "page":1,
  "size":2,
  "total":223,
  "results":[{
    "accountId":"5e184d95b1374eaf8b994bf3",
    "done":true,
    "id":"5e185bdcb1374eaf8b994bf7",
