Prox Server for Nature Remo Local API

Local API of Nature Remo has the following issues:

• Does not respond to HTTP OPTIONS method
• Does not respond if a request has many HTTP headers

Therefore, in order to call local API of Remo from the fetch API etc., you need a proxy server that responds to HTTP OPTIONS method, reduces the request headers, and calls the API. This application is a proxy server to achieve this.

Useage

First, install the required modules with the following command:

npm ci

Next, copy config/default.json to create config / production.json. Then change the settings in config/production.json as needed. The setting values mean the following:

name	type	description
httpServer.port	number	Port number used by the proxy server.
httpServer.accessControlAllowOrigin	string	The origin to which the CORS request responds. The specified value is set in access-control-allow-origin in the response header.
remoLocalApiOrigin	string	Origin of the Remo Local API. (e.g.: 'http://192.168.1.10')

Note: The setting values do not have to be in config/production.json as long as the contents are the same as in config/default.json.

After setting, the proxy server will start with the following command:

NODE_ENV=production node index.js

Now you can proxy requests to the Remo Local API to specified port on this server.
