sonyseng/json-caching-proxy

Node caching HTTP proxy built on top of express-http-proxy. Persists requests and responses to an in-memory HAR-like data structure based on HAR1.2 . Caches JSON content-type responses by default with the ability to cache an entire site; including content-types describing images. Useful for testing front end code, mocking api, and saving the cache to a HAR file which can be used for further tests.

json-caching-proxy's Issues

Binary cached content

First of all thank you so much for this wonderful tool. It has saved me really good amount of time during development. I have been successfully using it in one project but now when I tried to use it in another project all the cached content being served seems to be in binary, something like this:

��Q�&���O<K{�cS���������x�yV?���f��3C��<���s�9�6f�����b�����2eR������Tg���F������q�0��|Nbl_����5Ay �~Kxcc�

I can't figure out what the problem is. I have tried different node versions from 10.24.1 to 14.x. The requests when served first time are fine but later when they are served from cache the above is what I get. Any help would be much appreciated.

Expand abilities for controlling proxy through the browser

The current release allows the user to control the proxy through the browser by:

• Clear the entire cache
• Pause persisting to cache
• Pause replaying from the cache
• Downloading the cache into a HAR json file

It may be useful to add these features in an admin page:

• Display all the cached routes
• Search cached routes
• Alter cached routes
• Remove cached routes
• Exclude routes dynamically from being cached

POST/PUT requests may differ by POST/PUT body yet have the same URL Path

POST/PUTS that differ by the body content will seem identical and cause the proxy to playback an incorrect cache value. This will be fixed with the new file persistence scheme

Add options for TTL to invalidate cache

It may be useful to invalidate cache with a global TTL. And possibly a TTL based on regExp to target groups of routes or a specific one. The current TTL = infinity

How can I use this in typescript

First of all thank you so much for writing this. I have been using it for some time now, and it saves me a ton of time in development. I have a little bit of dynamic configuration based on the environment so I used the config in js file. Is there a way to use it in typescript without require?

Is it possible to save HAR automatically

Is it possible to save HAR automatically?

bodyParser is using a default limit. Allow modifying the limit as an option

Some POST requests have a large post body. Resulting in an HTTP 413 Payload too large Error. Allow the user to increase these limits.
