Feature

Filter

• escape filter is replaced by helper.escape which is provided by egg-security for better performance
• Add your filters to app/extend/filter.js, then they will be injected automatically to nunjucks

1// {app_root}/app/extend/filter.js
2exports.hello = name => `hi, ${name}`;
3
4// so you could use it at template
5// {app_root}/app/controller/test.js
6class TestController extends Controller {
7  async list() {
8    const ctx = this.ctx;
9    ctx.body = await ctx.renderString('{{ name | hello }}', { name: 'egg' }, {
10      path: '***'
11    });
12  };
13}

Tag

1// {app_root}/app.js
2const markdown = require('nunjucks-markdown');

4
5module.exports = app => {
6  markdown.register(app.nunjucks, marked);
7};
