## typescript | *.vue checker plugin for vite | esbuild | rollup

## Features

* Speeds up [TypeScript](https://github.com/Microsoft/TypeScript) type checking
* Supports [Vue Single File Component](https://vuejs.org/v2/guide/single-file-components.html)
* Displays nice error messages with the [code frame](https://babeljs.io/docs/en/next/babel-code-frame.html) formatter
* Prompt errors in Vite HMR overlay and terminal console
* Support both serve and build mode

**Motivation:** Vite and Esbuild are new and very fast build tools. But they do not have typescript type checking, as well as scripts in *.vue files. This plugin solves this problem. The "watch" mode is supported.

## Installation

```sh
# with npm
npm install --save-dev vite-esbuild-typescript-checker

# with yarn
yarn add -D vite-esbuild-typescript-checker
```

## Playground:
Examples of using the plugin are located in the "example" folder.
### EsBuild
```sh
cd example/esbuild
yarn install
yarn start
```
### EsBuild multiple entry points
```sh
cd example/esbuild2entry
yarn install
yarn start
```
### Vite
```sh
cd example/vite
yarn install
yarn dev | yarn build
```

## Vite example
```ts
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import { VitePlugin }  from 'vite-esbuild-typescript-checker';

export default defineConfig(({ command, mode, ssrBuild }) => {
    return {
        plugins: [vue(), VitePlugin({
            basedir: __dirname,
            watch: command === 'serve',
            vue: {
                enabled: true
            }
        }) as PluginOption]
    }
});
```
## Esbuild example
```js
import * as esbuild from "esbuild";
import { nodeExternalsPlugin } from "esbuild-node-externals";
import { EsbuildPlugin } from "vite-esbuild-typescript-checker";

esbuild.build({
    tsconfig: "./src/tsconfig.json",
    target: ["esnext"],
    entryPoints: ["src/index.ts"],
    watch: false,
    bundle: true,
    minify: false,
    sourcemap: true,
    platform: "node",
    outfile: "dist/index.js",
    plugins: [
        nodeExternalsPlugin({}),
        EsbuildPlugin({
            basedir: import.meta.dirname,
            watch: false
        })
    ]
}).catch(() => process.exit(1));
