Import Limelight

const { LimelightDB } = require("limelightdb"); // CommonJS
const Lime = require("limelightdb"); // CommonJS, for accessing all classes (Lime.LimelightDB, Lime.Database, Lime.Table)

import { LimelightDB } from "limelightdb"; // ES6
import * as Lime from "limelightdb"; // ES6, for accessing all classes (Lime.LimelightDB, Lime.Database, Lime.Table)

Database initialization:

new LimelightDB(filepath: string, humanReadable: boolean, key: string | null, port?: number).initialize();

If you want to decrypt your database before initialization, add the decrypt(...) method before the initialize() method.

new LimelightDB(filepath: string, humanReadable: boolean, key: string | null, port?: number).decrypt(key: string).initialize();

Providing a port will start an HTTP server on that port that can be used to access/modify your database externally, provided the port isn't already taken. You can interact with this server using the Sublime Admin Panel.


Database structure:

{
  "filename": "db.limelight",
  "humanReadable": true,
  "key": "secret_encryption_key",
  "encrypted": true,
  "tables": [
    {
      "name": "table",
      "cols": [
        "example",
        "example2"
      ],
      "rows": [
        {
          "example": "test",
          "example2": null
        }
      ],
      "schema": {
        "example": {
          "type": "string"
        },
        "example2": {
          "type": "null"
        }
      },
      "autoId": true
    }
  ]
}

Database interaction:

alter(table: string, changes: { schema: object, name: string, autoId: boolean })
select(table: string, filter: Function, limit?: number)
create(table: string, cols: string[], schema: object, autoId: boolean)
insert(table: string, rows: object[])
update(table: string, filter: Function, row: object)
delete(table: string, filter: Function)

read()

Interactions can also be done externally if a port is provided for the HTTP server to run on.

NOTE: For security, the server will only start if a key is required. Because the filter is just a JavaScript function, it could lead to remote code execution.

General Syntax: /query?type={{INTERACTION_TYPE}}&table={{TABLE_NAME}}&key={{ENCRYPTION_KEY}}
For additional parameters, use the same key names as are listed above.
All parameters must be URI Encoded. ((x => true) --> %28x%20%3D%3E%20true%29)
Examples:

GET /query?type=select&table=table&filter=%28x%20%3D%3E%20true%29&limit=5&key=secret_encryption_key
GET /query?type=alter&table=table&changes=%7B%20%22schema%22%3A%20%7B%20%22example%22%3A%20%7B%20%22type%22%3A%20%22number%22%20%7D%20%7D%20%7D&key=secret_encryption_key

Responses will have a success boolean, and depending on that, either code (error code) or response.

{
  "success": false,
  "code": "NO_INTERACTION_TYPE"
}

{
  "success": true,
  "response": [
    {
      "example": "test",
      "example2": null
    }
  ]
}

Schema examples
This uses AJV, so more details can be found there. User made schemas are only the properties property in the AJV schema object.
(Warning: Only the type property is guaranteed to work; everything else is "use at your own risk")

{
  "example": {
    "type": "string"
  },
  "example2": {
    "type": "null"
  }
}

Filter examples:

(x => x.example == "test")    // Returns row
(x => x["example"] == "test") // Returns row
(x => x.example2 == null)     // Returns row
(x => true)                   // Returns row
(x => x.example == null)      // Doesn't return row
(x => x.example2 == "test")   // Doesn't return row
(x => false)                  // Doesn't return row
