how to configure nextjs to see tsconfig.build.json instead of jsconfig.json when build?

[walt1992]

I have two config files for TypeScript. One is general tsconfig.json for the IDE, and another one is tsconfig.build.json to be used in real build. However, I don't know how to configure nextjs to use tsconfig.build.json file when it run on build.

Is there way to set for it?

It is actual! We need separate configs tsconfig.json for the IDE, and another one is tsconfig.build.json to be used in real build.

By the way, the only one way solve this problem temporarily is to disable type checking for production.
By adding this to the production config in next.config.js.

    typescript: {
      // !! WARN !!
      // Dangerously allow production builds to successfully complete even if
      // your project has type errors.
      // !! WARN !!
      ignoreBuildErrors: true,
    },

And optionally disable linting in package.json

"build": "next build --no-lint",

You can simply rename the tsconfig.build.json in tsconfig.json before running the build script.

If you run the build script in the CI, you can run something like:

script:
  - yarn install
  - mv tsconfig.build.json tsconfig.json
  - yarn build

There's a typescript option the next.config.js file:

  typescript: {
    tsconfigPath: './tsconfig.wonky.json',
  },

For example the above will look for './tsconfig.wonky.json' relative to the next.config.js file.

Thanks man, you saved my time! Is this option documented somewhere ? The only thing I can find is this link.

The above solution works for me. Using next v14.1.0. Thanks, @icyJoseph!
I'd say this question is answered.
