@gradientedge/axios-client

A simple factory function for creating an axios client for use in a nodejs environment. No options are required when calling the getAxiosClient function. In this case, default values will be used for the retry and HttpsAgent config.

Note that no HttpAgent config is provided. We expect all requests to be made via SSL and therefore the only agent we care about is HttpsAgent.

Minimal example:

import { getAxiosClient } from '@gradientedge/axios-client'

/**
 * No options provided, so this will use the default retry and HttpsAgent configuration.
 */
const client = getAxiosClient()

Full config override example:

import { getAxiosClient } from '@gradientedge/axios-client'

const client = getAxiosClient({
  httpsAgent: {
    keepAlive: false,
    timeout: 10000,
    maxSockets: 40,
    scheduling: 'lifo',
    
  },
  retry: {
    delayMs: 100,
    maxRetries: 5,  
  }
})

The client variable above is an AxiosInstance which gives you access to all the standard axios methods and functionality.

Default values via environment variables

The following describes below the environment variables which are read in, and which configuration options they apply to if supplied.

• REQUEST_TIMEOUT_MS => RequestConfig.httpsAgent.timeout
• REQUEST_MAX_SOCKETS => RequestConfig.httpsAgent.maxSockets
• REQUEST_RETRY_MAX_RETRIES => RequestConfig.retry.maxRetries
• REQUEST_RETRY_DELAY_MS => RequestConfig.retry.delayMs

If no values are specified for the config properties above, then the following fallback default values are used:

• RequestConfig.httpsAgent.timeout => 5000
• RequestConfig.httpsAgent.maxSockets => 20
• RequestConfig.retry.maxRetries => 5
• RequestConfig.retry.delayMs => 50
