.env
files provide a popular solution for defining environment variables, particularly in Node.js. Platforms like Heroku, for instance, use .env
files as part of their recommended best practices.
In this post, we’ll look at a simple Node.js application configured via environment variables, and explore how to customize an .env
file with new environment variables that override default values.
function getElementByXpath(path) { return document.evaluate(path, document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue; };function getElementsByXpath(xpath, parent) { let results = []; let query = document.evaluate(xpath, parent || document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null); for (let i = 0, length = query.snapshotLength; i < length; ++i) { results.push(query.snapshotItem(i)); } return results; }
