APIs have become an essential part of web development and are crucial for building modern applications. They allow developers to access functionalities provided by a web application, without having to build everything from scratch. This saves time and effort, enabling developers to focus on creating unique features while leveraging existing tools.

One such API is the Indic Keyboard API, which provides a set of methods to manipulate and render treebank structures. The API documentation can be found at https://aninditabasu.github.io/indica/html/rv.html.

To use this API, you first need to import it into your project. Here's an example of how to use the API to create a simple treebank:

const IndicKeyboard = require('IndicKeyboard');

const treebank = IndicKeyboard.createTreebank();

const node1 = treebank.createNode('Lexeme', 'cat');
const node2 = treebank.createNode('Morpheme', 'cat');

treebank.addNode(node1);
treebank.addNode(node2);

treebank.addEdge(node1, node2);

const result = treebank.toXML();

console.log(result);

This code imports the IndicKeyboard API and creates a treebank structure with two nodes and an edge connecting them. Finally, it logs the resulting XML string to the console.

The API also provides methods to manipulate existing treebanks. Here's an example of how to remove a node from an existing treebank:

const IndicKeyboard = require('IndicKeyboard');

const treebank = IndicKeyboard.createTreebank();

const node1 = treebank.createNode('Lexeme', 'cat');
const node2 = treebank.createNode('Morpheme', 'cat');

treebank.addNode(node1);
treebank.addNode(node2);

treebank.addEdge(node1, node2);

treebank.removeNode(node2);

const result = treebank.toXML();

console.log(result);

This code creates a treebank with two nodes and an edge connecting them. It then removes the second node and logs the resulting XML string to the console.

In conclusion, the Indic Keyboard API is a powerful tool that can greatly simplify the creation and manipulation of treebank structures. By using this API, developers can save time and effort while building more sophisticated applications.
