Package Exports

react-native-sqlite-manager
react-native-sqlite-manager/lib/commonjs/index.js
react-native-sqlite-manager/lib/module/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-native-sqlite-manager) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation

npm install react-native-sqlite-manager

Init DB

import { DB } from 'react-native-sqlite-manager';

function App(): JSX.Element {

  const [loading, setLoading] = useState(true); 

  useEffect(() => {
    setLoading(true)

    const db = DB.get("myApp.db")
    db.init(new Scheme(), /*db_version*/ 1).then(() => {
      setLoading(false)
    })

  }, []);

  if (loading) {
    return (
      <ActivityIndicator 
        animating={true} 
        size='large' 
        style={{flex: 1}}
      />
    )
  }

  return (
    <PaperProvider>
      <AppNavigator/>
    </PaperProvider>
  );
}

Scheme

import { ItScheme, table } from 'react-native-sqlite-manager';

export default class Scheme extends ItScheme {
    
  /**
   * When the database is created
   * @param db
   */
  async onCreate(db: DB) {
    console.debug("Scheme.onCreate")

    await db.executeSql(`
      CREATE TABLE IF NOT EXISTS tb_animals (
        id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, 
        name TEXT NOT NULL, 
        color TEXT NOT NULL, 
        age INTEGER NOT NULL, 
        timestamp INTEGER NOT NULL
      );
    `)
  }

}

Model

import { Model, Repository } from 'react-native-sqlite-manager';

export default class Animal extends Model {

  static get repository(): Repository {
    return {
      databaseName: 'myApp.db', 
      tableName: 'tb_animal',
    }
  }
  
}

Select

// SELECT * FROM tb_animals
const animals = await Animal.all()

// SELECT * FROM tb_animals WHERE id = 1
const animalById = await Animal.find(1)

// SELECT * FROM tb_animals WHERE age > 10
const animalByAge = await Animal.findBy("age", ">", 10)

// SELECT * FROM tb_animals ORDER BY ROWID ASC LIMIT 1
const firtsAnimal = await Animal.first()

// SELECT id, name, color FROM tb_animals 
// WHERE age > 8 AND age < 12
// ORDER BY name ASC 
// LIMIT 30 OFFSET 60

  columns: 'id, name, color',
  where: {
    clause: 'age > ? AND age < ?',
    args: [ 8, 12 ],
  },
  page: 3,
  limit: 30,
  order: 'name ASC'
})

// RAW Query
const { rows } = await Animal.executeSql(`
  SELECT id, name, color FROM tb_animals 
  WHERE age > ? AND age < ?
  ORDER BY name ASC 
  LIMIT 30 OFFSET 60
`, [
  8, 12
])

Insert, Update, Delete

// INSERT INTO tb_animals ...
const createdAnimal = await Animal.create({
  name: 'Bob',
  color: 'Brown',
  age: 2,
  timestamp: Date.now(),
})

// UPDATE tb_animals SET ...
const updatedAnimal = await Animal.update({
  id: 7,
  name: 'Bob',
})

// DELETE FROM tb_animals WHERE id = 8
await Animal.destroy(8)

const animalById = await Animal.find(1)
animalById.age = 12
await animalById.save()

DB Select

const db = DB.get('myApp.db')

await db.open()

// SELECT id, name, color FROM tb_animals 
// WHERE age > 8 AND age < 12
// ORDER BY name ASC 
// LIMIT 30 OFFSET 60
const animalsByQuery = await db.select('tb_animals', {
  columns: 'id, name, color',
  where: {
    clause: 'age > ? AND age < ?',
    args: [ 8, 12 ],
  },
  page: 3,
  limit: 30,
  order: 'name ASC'
})

// RAW Query
const { rows } = await db.executeSql(`
  SELECT id, name, color FROM tb_animals 
  WHERE age > ? AND age < ?
  ORDER BY name ASC 
  LIMIT 30 OFFSET 60
`, [
  8, 12
])

DB Insert, Update, Delete

// INSERT INTO tb_animals ...
const insertId = await db.insert('tb_animals', {
  name: 'Bob',
  color: 'Brown',
  age: 2,
  timestamp: Date.now(),
})

// UPDATE tb_animals SET ...
const rowsAffected = await db.update('tb_animals', {
  name: 'Bob',
}, {
  clause: 'id = ?',
  args: [7]
})

// DELETE FROM tb_animals WHERE id = 8
const rowsAffected = await db.delete('tb_animals', {
  clause: 'id = ?',
  args: [8]
})

Update database version

const db = DB.get("myApp.db")
db.init(new Scheme(), /*db_version*/ 2).then(() => {
  setLoading(false)
})

import { ItScheme, table } from 'react-native-sqlite-manager';

export default class Scheme extends ItScheme {
    
  /**
   * When the database is created
   * @param db
   */
  async onCreate(db: DB) {
    console.debug("Scheme.onCreate")

    await db.executeSql(`
      CREATE TABLE IF NOT EXISTS tb_animals (
        id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, 
        name TEXT NOT NULL, 
        color TEXT NOT NULL, 
        age INTEGER NOT NULL, 
        timestamp INTEGER NOT NULL,
        description TEXT NOT NULL
      );
    `)
  }
  
  /**
   * When the database version is updated
   * @param {DB} db
   * @param {number} oldVersion
   * @param {number} newVersion
   */
  async onUpdate(db: DB, oldVersion: number, newVersion: number) {
    console.debug("Scheme.onUpdate", oldVersion, newVersion)

    if (oldVersion != newVersion) {
      // update version db

      await table(db, "tb_animals").addColumns([
        new Column("description", "TEXT").defaultVal("") 
      ])
    }
  }
}
