I'm having a hard time to get Relay working within my monorepo. I have set everything up with Yarn workspaces (version berry) and Webpack 5.
When I'm trying to run one of my apps, I get the error:
MacroError: The macro you imported from "undefined" is being executed outside the context of
compilation with babel-plugin-macros. This indicates that you don't have the babel plugin
"babel-plugin-macros" configured correctly. Please see the documentation for how to configure
babel-plugin-macros properly:
https://github.com/kentcdodds/babel-plugin-macros/blob/master/other/docs/user.md
I also get 2 warnings:

I have already checked the sources of both, the babel-plugin-marcos and the babel-plugin-relay package and I could locate the lines of error (read here for further information) but I can't figure out what is going on.

Any tips welcome!
CodePudding user response：
Alright, I've got rid of the error by
- deleting the
.babelrcfile(s) - deleting the
babel-plugin-macros.config.jsfile(s) - adding the Relay plugin configuration to the
webpack.config.dev.ts
The relevant part of my webpack.config looks like this now
module: {
rules: [
{
test: /\.(ts|tsx)?$/,
use: {
loader: require.resolve("babel-loader"),
options: {
generatorOpts: { compact: false },
presets: [
"@babel/preset-env",
["@babel/preset-react", { runtime: "automatic" }],
"@babel/preset-typescript",
],
plugins: [
["relay", { artifactDirectory: "../../__generated__", eagerESModules: true }],
["@babel/plugin-transform-runtime"],
],
},
},
},
],
},
However, the two warnings still persist!

I have read that it might have to do with some asynchronous call of a macro!? Can I safely ignore these warnings? Is this a webpack issue?
Update ---
I have submitted an issue report at the Webpack GitHub Repo and according to them the babel-plugin-macros warning
Critical dependency: require function is used in a way in which dependencies cannot be statically extracted
is a result of something like
importSomeModules(require);
// or
const myRequire = require;
where require is not a call expression (eg: require(), require.resolve()).
In case of babel-plugin-macros this is
function macrosPlugin(babel,
// istanbul doesn't like the default of an object for the plugin options
// but I think older versions of babel didn't always pass options
// istanbul ignore next
{
require: _require = require,
resolvePath = nodeResolvePath,
isMacrosName = testMacrosRegex,
...options
} = {}) {}
Unfortunately, babel-plugin-macros is not being maintained anymore (though still a dependency for babel-plugin-relay).
The other warning coming from import-fresh
Critical dependency: the request of a dependency is an expression is a result of something like
let var1 = someCall();
require(var1); // webpack can't determine var1 value
Guess the affected line of the package can be found here.
