Discussion on: How to Create and Publish a React Component Library

[Kristin Bradley]

Great article! Very clear and easy to follow.

When importing the library I created into my test application, it worked great except I got this error: TS7016: Could not find a declaration file for module ... implicitly has an 'any' type.

It looks like I need to declare the module for my components but I'm unsure where to do this? I want to add this in the component library itself so users importing it won't see this error.

The output of the declaration files is covered in the "Adding Rollup" section. From this part of the rollup config in particular:

  {
    input: "dist/esm/types/index.d.ts",
    output: [{ file: "dist/index.d.ts", format: "esm" }],
    plugins: [dts()],
  },

Ok thanks. I double checked and I have that in my rollup.config.js file.
