express-middleware-har-replay

Express middleware for replaying a HAR archive of HTTP requests

Description

This middleware will let you create a server that replays requests captured in a HAR file.

Usage

npm install express-middleware-har-replay

const harreplayer = require('express-middleware-har-replay')
const app = express()
app.use(harreplayer({
  match: 'somehost.com',
  har: require('./my-har.json')
})
app.listen(8080)

Options

• har A plain JS object representing the contents of the HAR file.
• match The host to match.

The match option will tell the middleware which requests to replay. For example, if your HAR file has captured a GET http://example.com/foo/bar/baz, we can replay this request by providing 'example.com' as our match option, and later, dispatching a GET request to http://localhost:8080/foo/bar/baz.

Missing/TODO

• Publish ES5 code so it works on older versions of Node.
• More control over which requests to replay and how.
• Handle multiple requests to the same endpoint with different responses.
