Module Bundling

Depending on which libraries a project is dependent on, the rollup-plugin-node-builtins plugin may be required. In such cases, an error message similar to the following will be displayed at build time.

[ ERROR ]  Bundling Node Builtin
           For the import "crypto" to be bundled from
           commonjs-external:crypto, ensure the "rollup-plugin-node-builtins"
           plugin is installed and added to the stencil config plugins. Please
           see the bundling docs for more information.

In some cases, the rollup-plugin-node-globals plugin may also be required.

  1. Install both npm packages:
npm install rollup-plugin-node-builtins --save-dev
npm install rollup-plugin-node-globals --save-dev

And update the stencil.config.ts file including both plugins:

import { Config } from '@stencil/core';
+ import builtins from 'rollup-plugin-node-builtins';
+ import globals from 'rollup-plugin-node-globals';

export const config: Config = {
  namespace: 'mycomponents',
+  plugins: [
+    builtins(),
+    globals()
+  ]
