Installling

In order to install simply run the following command npm:

npm i @trust0/ridb --save

yarn:

yarn add @trust0/ridb

Usage

Creating your own database is pretty straight forward.

import {
    RIDB,
    SchemaFieldType
} from '@trust0/ridb';

(async () => {
    const db =  new RIDB({
        demo: {
            version: 0,
            primaryKey: 'id',
            type: SchemaFieldType.object,
            properties: {
                id: {
                    type: SchemaFieldType.string,
                    maxLength: 60
                }
            }
        }
    });
    console.log("Starting the database");
    await db.start({dbName: "demo"});
    console.log("Ok :)");
})()

Use with custom storage (IndexDB and InMemory)

import {
    RIDB,
    SchemaFieldType,
    StorageType
} from '@trust0/ridb';

(async () => {
    const db =  new RIDB({
        demo: {
            version: 0,
            primaryKey: 'id',
            type: SchemaFieldType.object,
            properties: {
                id: {
                    type: SchemaFieldType.string,
                    maxLength: 60
                }
            }
        }
    });
    console.log("Starting the database");
    await db.start({dbName: "demo", storage: StorageType.IndexDB //or StorageType.InMemory});
    console.log("Ok :)");
})()

Extra options for constructor:

• worker: boolean - Use a SharedWorker to offload the database to a shared worker across all tabs and extensions using it. Default is false.

Specification

Storage

A valid storage must extend BaseStorage class here's some example:

export class InMemory<T extends SchemaTypeRecord>  extends BaseStorage<T> {

    static create<SchemasCreate extends SchemaTypeRecord>(
        name: string,
        schemas: SchemasCreate,
        options: any
    ): Promise<
        BaseStorage<
            SchemasCreate
        >
    > {
        throw new Error("Method not implemented.");
    }

    constructor(name: string, schemas: T, options: any) {
        super(name, schemas, options);
    }

    findDocumentById(collectionName: keyof T, id: string): Promise<Doc<T[keyof T]> | null> {
        throw new Error("Method not implemented.");
    }
    find(collectionName: keyof T, query: QueryType<T[keyof T]>): Promise<Doc<T[keyof T]>[]> {
        throw new Error("Method not implemented.");
    }
    write(op: Operation<T[keyof T]>): Promise<Doc<T[keyof T]>> {
        throw new Error("Method not implemented.");
    }
    count(collectionName: keyof T, query: QueryType<T[keyof T]>): Promise<number> {
        throw new Error("Method not implemented.");
    }
    start(): Promise<void> {
        throw new Error("Method not implemented.");
    }
    close(): Promise<void> {
        throw new Error("Method not implemented.");
    }

}

Plugins

Plugins extend the functionality of the database by hooking into the database lifecycle.

/**
 * A simple plugin that overrides the docCreateHook and docRecoverHook methods.
 */
class MySimplePlugin extends BasePlugin {
    constructor() {
        super();
        this.docCreateHook = (
            schema,
            migration,
            docs
        ) => docs;
        this.docRecoverHook = (
            schema,
            migration,
            docs
        ) => docs;
    }
}
