rethinkdb-datatables
A Node.js RethinkDB query builder to be consumed by datatables.
Install
npm install rethinkdb-datatablesQuick start
server-side
var r = require('rethinkdb');
var queryBuilder = require('rethinkdb-datatables');
//Note: if you need to filter, don't use r.row here
//because this query will be nested when counting total records
var tableSelectionQuery = r.db('test').table('example');
var options = {
searchable: ['id', 'stringField', 'arrayField'],
pluckable: ['id', 'stringField', 'arrayField', 'timestamp'],
//primaryKey will then be used as the <td> row id in your html table by datatables
primaryKey: 'someOtherKey',
regexCaseSensitive: true
};
var defaultOptions = {
searchable: '<This will be built based on your initDatatables columns option>',
pluckable: '<This will be built based on your initDatatables columns option>',
primaryKey: 'id',
regexCaseSensitive: false
};
//No need for redundant try-catch anymore
queryBuilder.buildDataTablesQuery(paramsFromDataTables, r, tableSelectionQuery, options, function(err, preparedQuery) {
if (err) return cb(err);
r.connect({host: 'localhost'; port: 28015}, function(err, conn) {
//You may have to pass arrayLimit within run if you have > 100k documents
preparedQuery.run(conn, function(err, result) {
conn.close();
//Send response back depending on your framework i.e:
res.send(200, res);
});
