wSQL

wSQL - angularJS active record module for WebSQLite database - database in the browser. U can persist your data for your PhoneGap HTML5 applications build with ionic or angular. Good solution for mobile applications with offline mode.

install from bower

bower install angular-wsql

A sample of config file(u need to set your DB schema there) can be found in this repo at src/wSQL.db.config.js (just cope it in your project)

methods:

• wSQL.select()
• wSQL.insert(table_name, data)
• wSQL.batch_insert(table_name, data)
• wSQL.update(table_name, data)
• wSQL.delete(table_name)

optionally u can perform query directly with passing SQL

• wSQL.query(custom_sql)

optionally u can perform queries upon tables

• wSQL.create_table(table_name, table_fields)
• wSQL.drop_table(table_name)

methods to query request and generate results (all return promises):

• query - get all results
• row - get one row

• col - get one column

  
  
  ...
  .query().then(function(result){
      // query returns promise
      console.log(result);
  }, function(error){
      // error result
      console.log(error);
  })

### list of query modifiers:
* where
* where_in
* and
* and_in
* or
* or_in
* join
* left_join
* having
* set
* group_by
* order_by
* limit //limit also does offset as a second argument
