DCE + Edge
Use this skill when changing conditional require() paths, Node-only imports, or edge/runtime branching.
DCE-Safe require() Pattern
Webpack only DCEs a require() when it sits inside the dead branch of an if/else whose condition DefinePlugin can evaluate at compile time.
// CORRECT - webpack can eliminate the dead branch
if (process.env.__NEXT_USE_NODE_STREAMS) {
require('node:stream')
} else {
// web path
}
What does NOT work:don't have the plugin yet? install it then click "run inline in claude" again.
