npm install --save axios
Keep the endpoints in a separate file so we don’t have any machine numbers in the code
SalesHistory.jsx
Code that’s needed
endpoints.js
const JSON_SERVER = 'http://localhost:3000';
export const EP_SALES = '/sale';
export const REMOTE_HOST = JSON_SERVER;salesConnections.js

export const getSales = async (setGetError) => {
try {
const res = await axios.get(REMOTE_HOST + EP_SALES);
return res.data.length ? ({ sales: res.data }) : ({ error: `There are no todos stored` });
}
catch (e) {
setGetError(`Data not available from server: ${e.message}`)
