The module 'contentlayer/generated' or its type declarations are missing and cannot be located

Currently running NextJS 13.3 in my application directory and attempting to implement contentlayer for serving my mdx files.

tsconfig.json

{
    "compilerOptions": {
        ...
        "baseUrl": ".",
        "paths": {
            "contentlayer/generated": ["./.contentlayer/generated"]
        }
    },
    "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx", ".next/types/**/*.ts", ".contentlayer/generated"],
}

contentlayer.config.js

import { defineDocumentType, makeSource } from 'contentlayer/source-files';

export const Post = defineDocumentType(() => ({
    name: 'Post',
    contentType: 'mdx',
    filePathPattern: 'posts/*.mdx',
}));

export default makeSource({
    contentDirPath: 'content',
    documentTypes: [Post],
});

app/blog/[slug]/page.tsx

import { allPosts } from 'contentlayer/generated';

When trying to import, an error is triggered:

Error message: Cannot locate module 'contentlayer/generated' or its corresponding type declarations

Answer №1

For assistance with this issue on Github, refer to: https://github.com/contentlayerdev/contentlayer/issues/415

Remember to configure the settings in next.config.js(or next.config.mjs):

import { withContentlayer } from 'next-contentlayer'

export default withContentlayer({ ... })

In my situation, resolving the problem involved running the command yarn contentlayer dev(you can use npm, npx, or other package managers instead of yarn) after following the tutorial.

Answer №2

After discovering the issue (shoutout to @yejinc), I have added the contentlayer script to run in dev mode locally by updating the package.json:

"dev": "contentlayer dev & next dev"

Fortunately, it seems that this problem has been resolved in the most recent release of contentlayer: https://github.com/contentlayerdev/contentlayer/releases/tag/v0.3.2
