Groundwork-Water + React

Checkout Groundwork-Water Hooks
The data components library for USACE made in React + Groundwork

Hooks are made wrapping CWMSjs using code similar to the React example below.
They also provide variables for you to track the state, progress, and data of the request.
The header on the Groundwork-Water webpage provides a list of currently available hooks.

React + Vite Example

To Install: npm install cwmsjs --save

import { ParametersApi } from "cwmsjs";


const p_api = new ParametersApi();
p_api
    .getParametersRaw({
        office: 'SWT',
    })
    .then((r) => r.raw.json())
    .then((data) => {
        console.log(data?.parameters);
        console.log(data?.parameters?.parameters);
        Object.entries(data?.parameters?.parameters).forEach(([key, value]) => {
            console.log(value?.['abstract-param']);
            console.log(value?.['office']);
            console.log(value?.['default-english-unit']);
            console.log(value?.['default-si-unit']);

            console.log(value?.['description']);
        });
    })
    .catch(async (e) => {
        if (e.response) {
            const error_msg = e.response.json();
            e.message = `${e.response.url}\n${e.message}\n${JSON.stringify(error_msg, null, 2)}`;
            console.error(e);
            throw e;
        } else {
            throw e;
