Sample usage
Normal CommonJS
var newBatchHelper = require('web-sql-batch-helper').newBatchHelper;
var db = window.openDatabase('test.db', '1.0', 'Test', 5*1024*1024);
var helper = newBatchHelper(db);
var tx = helper.newBatchTransaction();
tx.executeStatement('DROP TABLE IF EXISTS tt');
tx.executeStatement('CREATE TABLE tt(a,b)');
tx.executeStatement('INSERT INTO tt VALUES(?,?)', [101, 'Alice']);
tx.commit().then(function() {
db.transaction(function(tx) {
tx.executeSql('SELECT * FROM tt', null, function(ignored, rs) {
alert('GOT RESULT LENGTH: ' + rs.rows.length + ' FIRST: ' + JSON.stringify(rs.rows.item(0)));
});
}, function(error) {
alert('step 2 error: ' + error.message);
});
});
or with sqlite plugin:
var newBatchHelper = require('web-sql-batch-helper').newBatchHelper;
var db = window.sqlitePlugin.openDatabase({name: 'test.db', location: 'default'});
var helper = newBatchHelper(db);
var tx = helper.newBatchTransaction();
tx.executeStatement('DROP TABLE IF EXISTS tt');
tx.executeStatement('CREATE TABLE tt(a,b)');
tx.executeStatement('INSERT INTO tt VALUES(?,?)', [101, 'Alice']);
tx.commit().then(function() {
db.transaction(function(tx) {
tx.executeSql('SELECT * FROM tt', null, function(ignored, rs) {
alert('GOT RESULT LENGTH: ' + rs.rows.length + ' FIRST: ' + JSON.stringify(rs.rows.item(0)));
});
}, function(error) {
alert('step 2 error: ' + error.message);
});
});
ES6
import {newBatchHelper} from 'web-sql-batch-helper';
const db = window.openDatabase('test.db', '1.0', 'Test', 5*1024*1024);
const helper = newBatchHelper(db);
const tx = helper.newBatchTransaction();
tx.executeStatement('DROP TABLE IF EXISTS tt');
tx.executeStatement('CREATE TABLE tt(a,b)');
tx.executeStatement('INSERT INTO tt VALUES(?,?)', [101, 'Alice']);
tx.commit().then(() => {
db.transaction((tx) => {
tx.executeSql('SELECT * FROM tt', null, function(ignored, rs) {
alert('GOT RESULT LENGTH: ' + rs.rows.length + ' FIRST: ' + JSON.stringify(rs.rows.item(0)));
});
}, (error) => {
alert('step 2 error: ' + error.message);
});
}, (error) => {
alert('BATCH ERROR: ' + error.message);
});
Then assemble the bundle using a tool such as RollupJS or JSPM.
GENERAL NOTE: Use of const
and let
may not work with some older browsers and devices. Possible solutions include:
- Just use
var
instead. - Use a tool like BabelJS (commonly used with JSPM, RollupJS, WebPack, etc.)
