Room-populate

Room-populate is a small Node.js library to pre-populate Room database for Android as described in Room documentation.

Introduction

See room-populate-demo project to see it in action

Usage

Installation:

npm install --save-dev room-populate

There is a single template-function populate:

    async  function createDb() {
        const db: Database = new Database("db.db");

        await populate("app/scr/schemas/1.json", db, function(this: Database): Promise<void> {
            return new Promise<void>(function(resolve, reject) {
                this.exec("INSERT INTO `playlists` (id, title, genre) VALUES (1, 'SAMPLE', 'JAZZ')", (err) => {
                    if (err) {
                        reject(err);
                    } else {
                        resolve();
                    }
                });
            });
        });

        db.close();
    }

The function performs:

1. Reads your schema
2. Sets-up a database with room setup
3. Creates tables
4. Populates tables with your statements supplied to populate
5. Creates indices
6. Creates views

If you need to alter creation/population order use RoomDbCreator to perform actions the way you prefer.
