@condor-labs/axios

Wrapper around axios using keepalive

See official documentation here.

Compatibility

The minimum supported version of Node.js is v8+.

How to use it

To use the library you just need to follow the following steps Install the library with npm

npm install @condor-labs/axios

Import the library:

const axios = require("@condor-labs/axios");

async function getUser() {
  try {
    const response = await axios.get("/user?ID=12345");
    console.log(response);
  } catch (error) {
    console.error(error);
  }
}

Environment Variables

Property	Type	Default	Description
AXIOS_KEEP_ALIVE_DISABLED	Boolean	FALSE	When true, keepalive is enabled for http and https agents in axios.
AXIOS_KEEP_ALIVE_MSECS	Number	1000	When using the keepAlive option, specifies the initial delay for TCP Keep-Alive packets. Ignored when the keepAlive option is false or undefined.
AXIOS_MAX_SOCKETS	Number	Infinity	Maximum number of sockets to allow per host. If the same host opens multiple concurrent connections, each request will use new socket until the maxSockets value is reached. If the host attempts to open more connections than maxSockets, the additional requests will enter into a pending request queue, and will enter active connection state when an existing connection terminates. This makes sure there are at most maxSockets active connections at any point in time, from a given host.
AXIOS_MAX_TOTAL_SOCKETS	Number	Infinity	Maximum number of sockets allowed for all hosts in total. Each request will use a new socket until the maximum is reached. This option is only available for NODEJS v12.19.0, v14.5.0.
AXIOS_MAX_FREE_SOCKETS	Number	256	Maximum number of sockets per host to leave open in a free state. Only relevant if keepAlive is set to true.
AXIOS_SOCKETS_SCHEDULING	String	'lifo'	Scheduling strategy to apply when picking the next free socket to use. It can be 'fifo' or 'lifo'. The main difference between the two scheduling strategies is that 'lifo' selects the most recently used socket, while 'fifo' selects the least recently used socket. In case of a low rate of request per second, the 'lifo' scheduling will lower the risk of picking a socket that might have been closed by the server due to inactivity. In case of a high rate of request per second, the 'fifo' scheduling will maximize the number of open sockets, while the 'lifo' scheduling will keep it as low as possible. This option is only available for NODEJS v12.20.0, v14.5.0.
AXIOS_SOCKETS_TIMEOUT	Number	4000 (4 secs)	Socket timeout in milliseconds. This will set the timeout when the socket is created.
