function runInterval(callback, interval = 1000) {
  setInterval(async () => {
    const results = await Promise.resolve(42) // this might fetch some data from server
    callback(results)

/*
 * Description:
 *
 * There are times when we want to re-use some data created/derived in a middleware later in a route handler.
 *
 * The default Koa way of doing so would be using `context.state`. Unfortunately `context.state` is hard to type and
 * quite implicit, since it's an object shared and potentially mutated by all middlewares and the route handler.

Theming Ant Design with Sass and Webpack

This is a solution on how to theme/customize Ant Design (which is written in Less) with Sass and webpack. Ant itself offers two solutions and a related article on theming, but these are only applicable if you use Less, the antd-init boilerplate or dva-cli.

What this solution offers:

• use a single sass-file to customize (no duplicate variables for your project and Ant)
• hot reload compatibility
• no dependencies on outdated npm modules
• easy integration with your existing webpack setup (webpack 3+ tested)
