Unstructured query language (UQL) - It is a query language to query the JSON like data in Javascript. Inspired by azure Kusto query language (KQL).
Install the UQL from npm/yarn
npm install uql
## or
yarn add uqlThen in your code use this as follows
import { uql } from "uql";
const users = [
{ name: "foo", age: 2, location: "uk" },
{ name: "bar", age: 3, location: "usa" },
];
const query = `order by "name" asc | project "name", "location"`;
uql(query, { data: users })
.then((res) => console.log(res))
.catch((ex) => console.error(ex));
//
// Output
//
// [ { name: 'bar', location: 'usa' }, { name: 'foo', location: 'uk' } ]A very simple ping query will respond you with pong.
A very simple echo query will echo what you said. Example: A query echo "hello world" will print hello world.
As the name suggests, count query will give you the length of an array. For example, the input [{},{}] and then the query count will respond with 2
The limit query, return up to the specified number of rows in an array like object. For example, the input [1,2,3] and then the query limit 2 will respond with [1,2]
limit query expects one mandatory argument which have to be a number
The order by query, sorts the items in the array into order by one or more columns. For example: order by "name" asc will order the input array by a field "name".
Note: field name should be referred by single quote and the order must be one of "asc" or "desc"
The project query, limits the field you want to return from the array of objects.
Example:
With [ { name: "foo", age: 1, country: "uk" }, { name: "bar", age :2, country: "usa" }], the query project "name", "age" will only return name and age properties of each element.
Note: field name should be referred by single quote.
The project-away query is opposite of project query. It omits the specified properties.
Example:
With [ { name: "foo", age: 1, country: "uk" }, { name: "bar", age :2, country: "usa" }], the query project-away "country", "age" will only return name property of each element.
Note: field name should be referred by single quote.
