| 토스 es-toolkit [빌드 설정 파일](https://github.com/toss/es-toolkit/blob/626af3b292fbd169f9f296d0e5edcdaa263b0f8f/rollup.config.mjs#L101)을 살펴보자. rollup을 이용하여 browser용으로 빌드할 때, `format: iife` 로 설정되어있는 것을 볼 수 있다. | ||
|
|
||
| ```js | ||
| // IIFE를 설정하여, 글로벌 네임스페이스 오염을 방지한다. | ||
| output: { | ||
| format: 'iife', | ||
| name, // "_"로 설정함. | ||
| file: outFile, | ||
| sourcemap, | ||
| generatedCode: 'es2015', | ||
| }, | ||
| }; | ||
| ``` | ||
|
|
||
|
|
||
|
|
||
| 직접 빌드해보면, 아래 내용을 가진 browser.global.js 로 빌드된 것을 볼 수 있다. | ||
|
|
||
| ```js | ||
| var _=function(t){"use strict";function at(t,e)...} | ||
| ``` | ||
|
|
||
|
|
||
|
|
||
| 이것을 script 형태로 사용한다면, 아래와 같이 사용할 수 있을 것이다. | ||
|
|
||
| ```html | ||
| <!-- 브라우저에서 직접 <script> 태그로 사용 가능 --> | ||
| <script src="browser.global.js"></script> | ||
| <script> | ||
| // 라이브러리가 전역 _ 변수로 노출됨 | ||
| _.someFunction(); | ||
| </script> | ||
| ``` |
