Error Consuming a StencilJS Component Library inside NextJS: A Comprehensive Guide to Fixing the Issue

Are you tired of encountering errors while trying to consume a StencilJS component library inside a NextJS project? You’re not alone! Many developers have faced this issue, but don’t worry, we’ve got you covered. In this article, we’ll take you through a step-by-step guide to help you troubleshoot and resolve this pesky error once and for all.

Understanding the Error: What’s Going On?

Before we dive into the solution, let’s take a closer look at the error itself. When you try to consume a StencilJS component library inside a NextJS project, you might encounter an error message that looks something like this:

Error: Error consuming StencilJS component library
Cannot find module './components/MyComponent' or its corresponding type declarations

This error occurs because NextJS is having trouble resolving the component imports from the StencilJS library. But fear not, dear developer, we’re about to break down the solution into manageable chunks.

Step 1: Verify Your Project Structure

Before we start troubleshooting, make sure your project structure is correct. Your directory structure should look something like this:

my-next-app/
node_modules/
@stencil/...
next/
...
components/
MyComponent.tsx
...
...

Ensure that your StencilJS component library is installed as a dependency in your `package.json` file:

"dependencies": {
  "@stencil/...": "^1.0.0"
}

Step 2: Check Your Component Imports

Next, review your component imports to ensure they’re correct. In your NextJS pages or components, you might have imports that look like this:

import { MyComponent } from '@stencil/MyComponent';

Verify that the import path is correct and matches the actual location of your StencilJS component library.

Step 3: Update Your NextJS Config

NextJS uses a specific configuration file called `next.config.js` to customize its behavior. Create or update this file to include the following settings:

module.exports = {
  //... other config options ...
  webpack: (config) => {
    config.module.rules.push({
      test: /\.tsx?$/,
      use: 'ts-loader',
      exclude: /node_modules/,
    });
    return config;
  },
};

This configuration tells NextJS to use the `ts-loader` for TypeScript files and excludes the `node_modules` directory from the loader.

Step 4: Implement Custom Webpack Resolvers

To help NextJS resolve the StencilJS component imports, you’ll need to implement custom Webpack resolvers. Create a new file called `webpack.resolvers.js` with the following content:

const path = require('path');

module.exports = {
  resolve: {
    alias: {
      '@stencil/MyComponent': path.resolve(__dirname, '../node_modules/@stencil/MyComponent'),
    },
  },
};

This resolver tells Webpack to look for the `@stencil/MyComponent` module in the `node_modules` directory.

Step 5: Update Your NextJS Page or Component

Finally, update your NextJS page or component to import the StencilJS component using the custom resolver:

import { MyComponent } from ' Alias: @stencil/MyComponent';

By using the `Alias:` syntax, you’re telling NextJS to use the custom resolver to import the `MyComponent` module.

Common Pitfalls to Avoid

As you’re troubleshooting, keep an eye out for these common pitfalls:

• Incorrect Import Paths: Double-check that your import paths match the actual location of your StencilJS component library.
• Missing or Incorrect Dependencies: Verify that you’ve installed the StencilJS component library as a dependency in your `package.json` file.
• Incorrect NextJS Config: Ensure that your `next.config.js` file is correctly configured to use the `ts-loader` and exclude the `node_modules` directory.
• Custom Resolver Issues: If you’re using a custom resolver, make sure it’s correctly configured and pointing to the correct location.

Conclusion

Error consuming a StencilJS component library inside NextJS can be a frustrating experience, but with these steps, you should be able to troubleshoot and resolve the issue. Remember to:

1. Verify your project structure and component imports.
2. Update your NextJS config to use the `ts-loader` and exclude the `node_modules` directory.
3. Implement custom Webpack resolvers to help NextJS resolve the StencilJS component imports.
4. Update your NextJS page or component to use the custom resolver.

By following these steps, you’ll be well on your way to successfully consuming your StencilJS component library inside your NextJS project.
