As stated in the documentation for https.request:

The following additional options from tls.connect() are also accepted when using a custom Agent: ca, cert, ciphers, clientCertEngine, key, passphrase, pfx, rejectUnauthorized, secureProtocol, servername.

This module allows to modify other options, as well as to disable them. For example, SNI can be disabled by setting servername to null (or undefined).

Install

$ npm i agent-options

Usage

• makeAgent(agentOptions) returns https.Agent created with given agentOptions and ensures that those agentOptions are used for tls.connect as well (in a sense of Object.assign).
• makeAgent(agentOptions, connectOptions) uses agentOptions for https.Agent (as is) and connectOptions for tls.connect (again, with Object.assign).

Examples

Performing https.request without SNI:

const https = require('https')
const makeAgent = require('agent-options')

const options = {
  host: 'example.com',
  port: 443,
  path: '/',
  agent: makeAgent({ servername: null })
}

const req = https.request(options, res => {
  res.on('data', data => {
    // ...
  })
  res.on('end', () => {
    // ...
  })
})

req.on('error', err => {
  // ...
})

req.end()

Same using got:

const got = require('got')
const makeAgent = require('agent-options')

got('example.com', { agent: makeAgent({ servername: null }) }).then(res => {
  // ...
}).catch(err => {
  // ...
})

Issues

• Support agents other than https.Agent?
