Question

结构：

|-server.js
|-views/
    |-master.njk
    |-index.njk

Koa-views配置：

logit("Koa-views : subfolder used: /views");
var views = views('./views', { //note that I removed the __dirname to test if it was the cause
    extension: 'njk',
    map: {
        njk: 'nunjucks'
    },
    options: {
        helpers: {
            uppercase: (str) => str.toUpperCase(),
            lowercase: (str) => str.toLowerCase(),
        },

    }
});
koa.use(views);

index.njk

{% extends "master" %}
{% block content %}
    <h1>Pretty lame content...</h1>
{% endblock %}

master.njk

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title></title>
    </head>
    <body>
        "Master page here" => {% block content %}{% endblock %}
    </body>
</html>

我验证每个文件都有chmod 777和相同的用户。如果我只替换1个变量并尝试使用渲染函数传递它，它就可以工作。但包括和延伸似乎是关闭。

我尝试了另一个带有另一个后端的项目并且它正在运行 - 但我还不够完整，无法查看所有源代码并弄清楚：（

我希望追溯更详细，没有完整的路径:(

修改我忘记了，这就是我称之为模板的方式

router.get('/', async function (ctx, next) {
    await ctx.render('index', {test: 'Hello'})
})

编辑2 我尝试使用koaNunjucks2 lib，当我将.njk放在我的扩展结束时，它必须与包koa-views有关。

Answer 1

试试这个。

const Koa = require('koa');
const views = require('koa-views');
const nunjucks = require('nunjucks');
const nunjucksEnvironment = new nunjucks.Environment(
    new nunjucks.FileSystemLoader(path.join(__dirname, './views'))
);

const koa = new Koa();

koa.use(views(path.join(__dirname, './views'), {
    extension: 'njk',
    options: {
        nunjucksEnv: nunjucksEnvironment
    },
    map: { njk: 'nunjucks' }
}));

Answer 2

const path = require('path');
const Koa = require('koa');
const app = new Koa();
const router = require('./routes/index');
const views = require('koa-views');
app.use(
  views(path.join(__dirname, 'views'), {
    extension: 'njk',
    map: { njk: 'nunjucks' },
    options: { settings: { views: path.join(__dirname, 'views') } }
  })
);
