RLP proxy (rewrite)

Proxy for react-link-preview.

Written from scratch to reimplement rlp-proxy, which is all rights reserved.

Features

• this proxy is based on puppeteer, therefore it is able to work with most sites, including react apps such as metahkg.org.
• more sites can be accessed with puppeteer-extra-plugin-stealth.
• uses fastify (instead of express)
• caching with mongodb, also caches null metadata
• auto delete successful caches after 30 days, null caches after 1 day
• 4 seconds timeout

Compatibility

• /v2 is highly compatible with the original rlp-proxy, however it DOES NOT give an error code when the site is not found / the site gives out any errors, simply returns { metadata: null }
• this proxy does not support v1, / is an alias of /v2

Other information

• rate limit:
  • cached: 200 / 30 seconds
  • uncached: 5 / 30 seconds
• Warning: slower since it uses puppeteer
• the querystring url should be UTF-8 encoded, or some urls may not be supported
