@progress/kendo-data-query
Advanced tools
@progress/kendo-data-query is a package that provides utilities for querying and manipulating data collections. It is particularly useful for operations such as sorting, filtering, grouping, and aggregating data in JavaScript applications.
Sorting
The `orderBy` function allows you to sort an array of objects based on specified fields and directions. In this example, the data is sorted by the 'age' field in ascending order.
const { orderBy } = require('@progress/kendo-data-query');
const data = [{ name: 'John', age: 30 }, { name: 'Jane', age: 25 }];
const sortedData = orderBy(data, [{ field: 'age', dir: 'asc' }]);
console.log(sortedData);Filtering
The `filterBy` function allows you to filter an array of objects based on specified criteria. In this example, the data is filtered to include only objects where the 'age' field is greater than 26.
const { filterBy } = require('@progress/kendo-data-query');
const data = [{ name: 'John', age: 30 }, { name: 'Jane', age: 25 }];
const filteredData = filterBy(data, { field: 'age', operator: 'gt', value: 26 });
console.log(filteredData);Grouping
The `groupBy` function allows you to group an array of objects based on specified fields. In this example, the data is grouped by the 'age' field.
const { groupBy } = require('@progress/kendo-data-query');
const data = [{ name: 'John', age: 30 }, { name: 'Jane', age: 25 }, { name: 'Doe', age: 30 }];
const groupedData = groupBy(data, [{ field: 'age' }]);
console.log(groupedData);Aggregating
The `aggregateBy` function allows you to perform aggregate operations on an array of objects. In this example, the sum of the 'age' field is calculated.
const { aggregateBy } = require('@progress/kendo-data-query');
const data = [{ name: 'John', age: 30 }, { name: 'Jane', age: 25 }, { name: 'Doe', age: 30 }];
const aggregates = aggregateBy(data, [{ field: 'age', aggregate: 'sum' }]);
console.log(aggregates);Lodash is a popular utility library that provides a wide range of functions for manipulating arrays, objects, and other data types. It includes functions for sorting, filtering, grouping, and aggregating data, similar to @progress/kendo-data-query. However, Lodash offers a broader set of utilities beyond data querying.
Underscore is another utility library that provides a variety of functions for working with arrays, objects, and other data types. It includes functions for sorting, filtering, grouping, and aggregating data. While similar to Lodash, Underscore has a smaller footprint and a slightly different API.
Ramda is a functional programming library for JavaScript that emphasizes immutability and side-effect-free functions. It provides utilities for data manipulation, including sorting, filtering, grouping, and aggregating. Ramda's API is designed to be more functional and composable compared to @progress/kendo-data-query.
