@npmcli/agent

A pair of Agent implementations for nodejs that provide consistent keep-alives, granular timeouts, dns caching, and proxy support.

Usage

const { getAgent, HttpAgent } = require('@npmcli/agent')
const fetch = require('minipass-fetch')

const main = async () => {
    // if you know what agent you need, you can create one directly
    const agent = new HttpAgent(agentOptions)
    // or you can use the getAgent helper, it will determine and create an Agent
    // instance for you as well as reuse that agent for new requests as appropriate
    const agent = getAgent('https://registry.npmjs.org/npm', agentOptions)
    // minipass-fetch is just an example, this will work for any http client that
    // supports node's Agents
    const res = await fetch('https://registry.npmjs.org/npm', { agent })
}

main()

Options

All options supported by the node Agent implementations are supported here, see the docs for those.

Options that have been added by this module include:

• family: what tcp family to use, can be 4 for IPv4, 6 for IPv6 or 0 for both.
• proxy: a URL to a supported proxy, currently supports HTTP CONNECT based http/https proxies as well as socks4 and 5.
• dns: configuration for the built-in dns cache
  • ttl: how long (in milliseconds) to keep cached dns entries, defaults to 5 * 60 * 100 (5 minutes)
  • lookup: optional function to override how dns lookups are performed, defaults to require('dns').lookup
• timeouts: a set of granular timeouts, all default to 0
  • connection: time between initiating connection and actually connecting
  • idle: time between data packets (if a top level timeout is provided, it will be copied here)
  • response: time between sending a request and receiving a response
  • transfer: time between starting to receive a request and consuming the response fully
