# --description--
|
||
|
||
请注意,本项目在 [这个 Repl.it 项目](https://repl.it/github/freeCodeCamp/boilerplate-mochachai) 的基础上进行开发。你也可以从 [GitHub](https://repl.it/github/freeCodeCamp/boilerplate-mochachai) 上克隆。
|
||
|
||
你可以在应用的模版引擎中使用静态模板文件(如那些写在 *Pug* 里的)。在运行时,模版引擎会用服务端的真实数据替换掉模版文件中的变量,然后将模版转译成发送给客户端的 HTML 静态文件。这样可以轻松地构造 HTML 页面,允许在页面直接显示变量内容而不需要发送 API 请求。
|
||
|
||
为了在项目中使用 *Pug*,你需要在 package.json 中添加依赖 `"pug": "^0.1.0"`。注意,依赖的名称和版本号都要添加。
|
||
|
||
为了在 Express 中使用 pug 作为模版引擎,你需要在 express 中将 **app** 的 "view-engine" 设置为 "pug",就像这样:`app.set('view engine', 'pug')`。
|
||
|
||
如果没有正确的 *render* *'views/pug'* 路径下的 index 文件,页面将不会被加载。
|
||
|
||
最后, 你需要修改 `res.render()` 方法,设置 `/` 的响应。`res.render()` 方法接收一个文件路径作为参数,这个路径既可以是相对路径(相对于 views),也可以是绝对路径。而且,我们不需要给它添加文件扩展名(文件后缀名)。
|
||
|
||
如果一切顺利,刷新一下应用的主页就不会看到 "Pug template is not defined." 的报错了,而是会看到 Pug 成功加载的提示。
|
||
|
||
完成上述要求后,你可以在下方提交你的页面链接。如果你遇到了问题,可以参考 [这里](https://gist.github.com/camperbot/3515cd676ea4dfceab4e322f59a37791) 的答案。

# --hints--
|
||
|
||
项目中应使用 Pug 作为依赖。
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.get(getUserInput('url') + '/_api/package.json').then(
|
||
(data) => {
|
||
var packJson = JSON.parse(data);
|
||
assert.property(
|
||
packJson.dependencies,
|
||
'pug',
|
||
'Your project should list "pug" as a dependency'
|
||
);
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.statusText);
|
||
}
|
||
);
|
||
```
|
||
|
||
项目中应使用 Pug 作为模版引擎。
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.get(getUserInput('url') + '/_api/server.js').then(
|
||
(data) => {
|
||
assert.match(
|
||
data,
|
||
/('|")view engine('|"),( |)('|")pug('|")/gi,
|
||
'Your project should set Pug as a view engine'
|
||
);
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.statusText);
|
||
}
|
||
);
|
||
```
|
||
|
||
在 Response 里使用正确的 ExpressJS 方法渲染主页面。
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.get(getUserInput('url') + '/').then(
|
||
(data) => {
|
||
assert.match(
|
||
data,
|
||
/FCC Advanced Node and Express/gi,
|
||
'You successfully rendered the Pug template!'
|
||
);
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.statusText);
|
||
}
|
||
);
|
||
```
|
||
|
||
Pug 应该生效。
|
||
|
||
```js
|
||
(getUserInput) =>
|
||
$.get(getUserInput('url') + '/').then(
|
||
(data) => {
|
||
assert.match(
|
||
data,
|
||
/pug-success-message/gi,
|
||
'Your projects home page should now be rendered by pug with the projects .pug file unaltered'
|
||
);
|
||
},
|
||
(xhr) => {
|
||
throw new Error(xhr.statusText);
|
||
}
|
||
);
|
||
```
