CI-Node-query
A node query builder for various SQL databases, based on CodeIgniter's query builder.
Features
- Callback and Promise API for making database calls.
Supported databases
- Mysql (via
mysql2) - PostgreSQL (via
pg) - Sqlite (via
dblite)
Installation
npm install ci-node-query
Basic use
// Set the database connection details
const nodeQuery = require('ci-node-query')({
"driver": "mysql",
"connection": {
"host": "localhost",
"user": "test",
"password": "",
"database": "test"
}
});
// Get the query builder
const query = nodeQuery.getQuery();
query.select('foo')
.from('bar')
.where('x', 3)
.orWhere({y: 2})
.join('baz', 'baz.boo = bar.foo', 'left')
.orderBy('x', 'DESC')
.limit(2, 3)
.get(function(/* Adapter dependent arguments */) {
// Database module result handling
});
// As of version 3.1.0, you can also get promises
var queryPromise = query.select('foo')
.from('bar')
.where('x', 3)
.orWhere({y: 2})
.join('baz', 'baz.boo = bar.foo', 'left')
.orderBy('x', 'DESC')
.limit(2, 3)
.get();
queryPromise.then(function(res) {
// Handle query results
});
Security notes
As of version 2, where and having type methods parse the values passed to look for function calls. While values passed are still passed as query parameters, take care to avoid passing these kinds of methods unfiltered input. SQL function arguments are not currently parsed, so they need to be properly escaped for the current database.
