In plain English

Zero Server is a web framework that lets you build websites and web applications without the usual setup work. Instead of configuring build tools, routing systems, or package managers before you write a single line of code, you just create a folder and start adding files. Zero handles the rest automatically. The core idea is file-system routing. If you create a file called api/login.js, your site automatically exposes it at http://yoursite.com/api/login. No configuration files required. When your code needs a library and you call require inside a JavaScript file, Zero installs that package for you without you having to run any install commands yourself. One of Zero's more distinctive features is support for mixing different programming languages in the same project. You could have a Python file serving a machine-learning model as an API endpoint, React pages consuming that API, Node.js handling user authentication, and plain HTML for static pages, all living in the same folder and running as one application. Supported languages include Node.js, React, Vue, Svelte, HTML, Markdown with embedded components (called MDX), and Python. Zero also handles bundling and server-side rendering automatically. When you write a React page, you do not need to set up webpack or configure server-side rendering yourself. The framework detects what you have written and compiles it appropriately. Hot module replacement means changes in development show up in your browser without a full page reload. This tool is aimed at developers who want to prototype quickly or who find modern JavaScript build tooling tedious to configure. It is particularly useful if you are building a small web application or API and do not want to spend time on setup before getting to the actual product. The project is licensed under Apache 2.0, which permits commercial use.

Copy-paste prompts

Prompt 1
I have a Zero Server project. My React index.jsx page needs to fetch data from my Python api/model.py endpoint. Write the React component using getInitialProps to call /api/model and display the result.
Prompt 2
Set up a Zero Server project with a Node.js login endpoint at api/login.js that accepts POST requests with email and password, and return a JSON token.
Prompt 3
I want to add a Vue counter page to my Zero Server project. Write the component I should save as counter.vue so it auto-routes to /counter.
Prompt 4
My Zero Server project needs a specific version of lodash. Show me how to add a package.json that pins lodash to 4.17.21 while Zero still auto-installs everything else.
