# Backends
|
|
|
|
Frappe.js comes with built-in backends for data storage. These can be client-side or server-side
|
|
|
|
- SQLite
|
|
- REST
|
|
|
|
There can be only one backend at a time that can be accessed by the `frappe.db` property.
|
|
|
|
## API
|
|
|
|
The backend will implement the following `async` methods
|
|
|
|
- `get_doc`
|
|
- `get_all`
|
|
- `get_value`
|
|
- `insert`
|
|
- `update`
|
|
|
|
## sqlite Backend
|
|
|
|
Connection paramter required for the sqlite backend is the path of the file
|
|
|
|
```js
|
|
sqllite = require('frappejs/frappe/backends/sqlite');
|
|
|
|
frappe.db = await new sqlite.Database({db_path: db_path})
|
|
```
|
|
|
|
### SQL Queries
|
|
|
|
You can also directly write SQL with `frappe.db.sql`
|
|
|
|
```js
|
|
all_todos = frappe.db.sql('select name from todo');
|
|
```
|
|
|
|
## REST Backend
|
|
|
|
For the client, the backend is the REST API that executes calls with web-requests.
|
|
|
|
Before using, you must initialize the `frappe.fetch` property with `window.fetch` or `node-fetch`
|
|
|
|
```js
|
|
const Database = require('frappejs/frappe/backends/rest_client').Database;
|
|
|
|
frappe.fetch = window.fetch.bind();
|
|
frappe.db = await new Database({server: server});
|
|
``` |
