d3-tip with browserify and webpack

d3-tip-browserify.js

let d3 = require("d3");
let d3tip = require("d3-tip");
d3tip(d3);

d3-tip-webpack.js

import d3 from "d3";
import d3Tip from "d3-tip";
d3.tip = d3Tip;

create-react-app 3.3.1
d3 5.12
d3-tip 0.9.1

None of the above worked for me. This did:

import * as d3 from "d3"
import d3Tip from "d3-tip"
const tip = d3Tip().attr(...).html(...)

This worked for me, using [email protected], [email protected], and [email protected].

import * as _d3 from 'd3';
import _d3Tip from 'd3-tip';
const d3 = {..._d3, tip: _d3Tip};

create-react-app 3.3.1
d3 5.12
d3-tip 0.9.1

None of the above worked for me. This did:

import * as d3 from "d3"
import d3Tip from "d3-tip"
const tip = d3Tip().attr(...).html(...)

thank you!!!
