🗝 Koa Vault

Archive Koa responses, for historical purposes.

This project will save JSON responses to a local directory, which can be later used when the API is decommissioned. Read about why this project was created here.

Could be used with koa-proxy to scrape arbitrary API's.

Installation

yarn add koa-vault

Usage

// ecmascript module
import vault from 'koa-vault'

// commonjs
const vault = require('koa-vault')

app.use(
  vault({
    directory: './vault', // default
    offline: false //default
  })
)

Saved files

→ program → mulatu-astatke.json
→ program → nakhane.json
→ program → neneh-cherry.json
→ program → oneohtrix-point-never.json

JSON files will be saved to the vault directory. Due to file naming conventions, forward slashes are replaced with forward arrows (→), and question marks with question blocks (░).

Only GET requests with application/json content-type header responses will be saved. If this does not suit your needs, please open a pull request.

Offline/archive

When turning the offline option on, GET requests will be served from the vault directory. If the file does not exist, a 404 error will be thrown.
