设置“basedir"NestJS 中的 Pug 选项

问题描述

我正在尝试在 NestJS 中使用 pug 布局，但是当从绝对路径扩展布局时，pug 需要 basedir 要设置的选项.

I'm trying to use pug layouts in NestJS, however when extending a layout from an absolute path, pug requires the basedir option to be set.

在 ExpressJS 中你会使用 app.locals.basedir = ...，那么 NestJS 中的等价物是什么?

In ExpressJS you would use app.locals.basedir = ..., what would be the equivalent in NestJS?

const server = await NestFactory.create<NestExpressApplication>(AppModule);
server.setViewEngine('pug');
server.setBaseViewsDir(join(__dirname, 'templates', 'views'));
await server.listen(config.server.port);

在视图中使用 extends/layouts/index 会抛出以下内容；basedir"选项需要使用包含和绝对"路径扩展.

Using extends /layouts/index in a view would throw the following; the "basedir" option is required to use includes and extends with "absolute" paths.

我不打算使用相对路径，因为这很快就会变得非常混乱.例如.扩展../../../layouts/index

I'm not looking to use relative paths, since this quickly becomes very messy. E.g. extends ../../../layouts/index

推荐答案

翻阅文档后，NestJS 在幕后使用了一个 express，并通过 getHttpAdapter().getInstance().

After looking around through the documentation, NestJS uses an express under the hood, and gives you access to the underlying instance with getHttpAdapter().getInstance().

记住这一点，我们可以如下设置basedir；

Keeping that in mind, we can set the basedir as follows;

const express = server.getHttpAdapter().getInstance();
express.locals.basedir = join(__dirname, 'templates');
