如何区分 Svelte 开发模式和构建模式? [英] How to differentiate between Svelte dev mode and build mode?

问题描述

dev模式使用npm run dev，release模式使用npm build

我怎么知道它当前是建立在开发模式还是不在代码中，例如:

解决方案

不确定正确的方法.我分享了我在我的项目中所做的事情.

1. 在rollup.config.js

<块引用>

从@rollup/plugin-replace"导入替换；const 生产 = !process.env.ROLLUP_WATCH;

2. 在 plugins:[ ] 块中添加这个

<块引用>

替换({isProduction: 生产,}),

rollup.config.js 看起来像这样.

},插件: [代替({isProduction: 生产,}),苗条({

3. 然后在组件内部使用 isProduction.

<块引用>

if (!isProduction){ console.log('开发模式');}

The dev mode using npm run dev, the release mode using npm build

How could i know that it's currently built on dev mode or not in the code, for example:

<script>
    import {onMount} from 'svelte';

    onMount(function(){
        if(DEVMODE) { // --> what's the correct one?
            console.log('this is x.svelte');
        }
    })
</script>
 

解决方案

Not sure about the correct method. I share what I did on my project.

1. in rollup.config.js

import replace from "@rollup/plugin-replace";
const production = !process.env.ROLLUP_WATCH;

2. inside plugins:[ ] block add this

replace({
          isProduction: production,
      }),

rollup.config.js will look like this.

},
    plugins: [
        replace({
            isProduction: production,
        }),
        svelte({
            

3. Then use isProduction inside components .

if (!isProduction){ console.log('Developement Mode'); }
