seanparmelee / ld-server-nextjs

This is a Next.js project bootstrapped with create-next-app.

This project reproduces an error that occurs when trying to use @launchdarkly/node-server-sdk in a Next.js application.

To reproduce the issue

Run the following commands:

npm install
npm run build

Which should result in

Failed to compile.

./lib/ld-server.ts
Module not found: Default condition should be last one

https://nextjs.org/docs/messages/module-not-found

Import trace for requested module:
./pages/index.tsx

To resolve the issue

Open node_modules/@launchdarkly/node-server-sdk/package.json and for each entry in the exports field, move the default entry to the end.

For example, update:

  "exports": {
    ".": {
      "default": "./dist/src/index.js",
      "types": "./dist/src/index.d.ts"
    },
    "./integrations": {
      "default": "./dist/src/integrations.js",
      "types": "./dist/src/integrations.d.ts"
    }
  },

to

  "exports": {
    ".": {
      "types": "./dist/src/index.d.ts",
      "default": "./dist/src/index.js"
    },
    "./integrations": {
      "types": "./dist/src/integrations.d.ts",
      "default": "./dist/src/integrations.js"
    }
  },

and then run

npm run build
