# `vuepress-plugin-netlify-functions`

English | [简体中文](./README.md)

If your vuepress site is deployed on `netlify` and you want to be able to use `netlify functions` for `serverless`.

You may need this plugin to provide support.

## Features

- On the Vuepress local server, start a `Netlify Functions` local service to help you debug `functions` locally.
- Generate a usable `netlify.toml` and add the appropriate 'functions' configurations if you have already created`netlify.toml`
- This plugin does not provide specific `function` scripts, only `netlify functions` support;
  It can be used directly in themes, directly in vuepress projects, or based on this plugin,
  new plugins can be developed to provide more detailed functionality support.
- Use `dotenv` to provide support similar to `Netlify Environment variables` in the local service
  environment. Create `.env` files in the project root directory to hold development-time environment variables

npm install vuepress-plugin-netlify-functions
