Generating _redirects in 11ty
I enjoy using 11ty. In this article by Aleksandr I learned, how I can generate a _redirect file out of my front matter data
Today I updated an article that is about automatically switching Node.js version with nvm. In the course of this I wanted to delete two old articles and bring them to the current article via an HTTP redirect.
As I host my blog on Netlify, all I need is a _redirects file with the redirects:
/old-url/ /new-url/
/old-url-2/ /new-url/At first I wanted to create this by hand, but then I came across an article by Aleksandr and now I generate the file automatically. The great thing is: I can specify in my articles, which pages should link to the respective article.
The _redirects file is generated out of my template file redirects.njk:
---
permalink: /_redirects
eleventyExcludeFromCollections: true
---
{%- for page in collections.all -%}
{%- if page.url and page.data.redirectFrom -%}
{%- for oldUrl in page.data.redirectFrom %}
{{ oldUrl }} {{ page.url }}
{%- endfor -%}
{%- endif -%}
{%- endfor -%}
To get the _redirects file mentioned above I define redirectFrom in the front matter of my new article
redirectFrom:
- /old-url/
- /old-url-2/
I enjoy using 11ty and it is great how far you can get with it.
