Using Tern with create-react-app apps / Tern webpack-resolver out-of-date?

[ELLIOTTCABLE]

So, I'm not entirely sure, but it looks like perhaps create-react-app's react-scripts' Webpack config is doing something a little more complicated than Tern's Webpack plugin can understand?

Here's the .tern-project config I tried, basically from this reference:

{
  "libs": [
    "browser"
  ],
  "loadEagerly": [],
  "dontLoad": [],
  "plugins": {
    "modules": {},
    "webpack": {
      "configPath": "./node_modules/react-scripts/config/webpack.config.js"
    }
  }
}

I get this error-message:

$ NODE_ENV=development tern --verbose
test-proj/node_modules/react-dev-utils/ModuleScopePlugin.js:22
    resolver.hooks.file.tapAsync(
                   ^

Reproduction:

nodenv local 10.12.0
npm install --global yarn [email protected]

npx create-react-app test-proj && cd test-proj
jq -n -j '.["plugins"]["webpack"]["configPath"] = "./node_modules/react-scripts/config/webpack.config.js"' > .tern-project
NODE_ENV=development tern --verbose

Possibly-relevant version numbers:

Node: 10.12.0 (reproduces on v8.x.x, as well) Tern: 0.23.0 create-react-app: 2.1.2 react-scripts: 2.1.2 Webpack: 4.19.1

How about webpackDevServer.config.js

./node_modules/react-scripts/config/webpackDevServer.config.js
