@forsakringskassan/vite-lib-config

Toolchain for building Vue framework libraries.

• Hybrid ESM/CJS packages.
• Transpiled with Babel.
• Supports monorepo.

Configuration

Bundled dependencies

By default all dependencies (dependencies and peerDependencies) are marked as external and not bundled in output files. This can be overriden by setting externalDependencies in package.json:

     "dependencies": {
         "lodash": "^4.17.20"
     },
+    "externalDependencies": [
+        "lodash"
+    ],

Usage

babel.config.js

module.exports = {
    presets: ["@forsakringskassan/vite-lib-config/babel"],
};

vite.config.ts

import { defineConfig } from "@forsakringskassan/vite-lib-config/vite";

export default defineConfig();

In addition to the regular Vite configuration you can also pass the optional fk property:

export interface FKConfig {
    /** path to component to mount by default (default `src/dev-vite/app.vue`) */
    entrypoint?: string;
    /** mocks to configure with apimock-express (default `[]`) */
    mocks?: MockEntry[];
}

package.json

{
    "scripts": {
        "build": "fk-build-vue-lib"
    }
}

Optional: API Extractor

 {
     "scripts": {
         "build": "fk-build-vue-lib",
+        "postbuild": "fk-api-extractor api-extractor.json",
     }
 }

Multiple files or globs can be given:

fk-api-extractor api-extractor.*.json

To fix global module augmentations use:

fk-api-extractor --patch-augmentations

Use --help to see full description.

Dev-server

{
    "scripts": {
        "start": "vite"
    }
}

Create src/local.{ts,mts,mjs,js} exporting a single function setup:

import { createApp } from "vue";
import { type SetupOptions } from "@forsakringskassan/vite-lib-config";

export function setup(options: SetupOptions): void {
    const { rootComponent, selector } = options;
    const app = createApp(rootComponent);
    app.mount(selector);
}

If the setup function is async (i.e. returns a Promise) it will be awaited before continuing.

Create src/vite-dev/app.vue containing the root component you want to serve as a development environment.

Appending Plugins

If you need to use custom plugins in your library, remember to also include the default plugins, these will otherwise by overwritten.

vite.config.ts

import {
    defineConfig,
    defaultPlugins,
} from "@forsakringskassan/vite-lib-config/vite";

export default defineConfig({
    plugins: [...defaultPlugins, myFancyPlugin],
});
