Smallest Backend ever

• Easiest way for creating a key/value Store on a (FTP) Server
• PHP based
• Store a e.g. a JSON-Array on a Server
• Just upload the php file
• Caution: No security at all

Caution

There is no security layer implemented. This tool should not be used for production systems and is no replacement for a real middleware system with based on a framework and with a real database.

Getting started

Server

• Upload the whole project forder smallest_backend_ever file to your FTP server
• Change the folder rights to 777

Frontend

• Add the file mini_backend.js to your project
• Include the JS file to your project: <script src="./mini_backend.js"></script>
• Set the URL to in your JavaScript to the URL of the PHP file on your Server: setURL('http://developerakademie.com/smallest_backend_ever'); (e.g. to the init() method)
• Load, save and delete text similar to the localStorage API
• You might need to install a plugins to bypass CORS, e.g. this one
• Use a live server for local Development

Examples

If you want to see a full working example, open the file example.html. Imagine we're having an array of users:

let users = [];

Save

Add a user with this function:

function addUser() {
    users.push('John);
    backend.setItem('users', JSON.stringify(users));
}

If you want to wait for the request you can add the await keyword as well:

Add a user with this function:

async function addUser() {
    users.push('John);
    await backend.setItem('users', JSON.stringify(users));
}

Load

Fill your empty array with users from the Server

async function init() {
    await downloadFromServer();
    users = JSON.parse(backend.getItem('users')) || [];
}

Delete

Delete all users from your array:

function deleteUser(name) {
  await backend.deleteItem('users');
}
