Blog Tools

blog-tools is a collection of tools that helps make blogs in Rust.

For this to work, you should have a folder, for instance, blog which serves as the root. Within this folder, you must have the following structure

  • blog
    • 2023
      • 2023-01-01
        • my_first_blog.json
        • my_first_blog.md
      • (other folders)

That is, organised by year, organised by date (yyyy-mm-dd), then a blog.md next to a blog.json.

The JSON must conform to the following schema

{
"title": String,
"date": ISO 8601 Date i.e. YYYY-MM-DD,
"desc": Optional<String>,
"slug": String,
"tags": [String],
"keywords": Optional<[String]>,
"canonical_link": Optional<String>,
"author_name": Optional<String>,
"author_webpage": Optional<String>,
"last_modified": Optional<Date>, (ISO 8601)
"priority": Optional<float>
}

Slugs

In blog-tools all slugs are /{date}/{sub-slug}.

Make sure the "slug" filed in the JSON is just the final sub-slug

How This Crate is Organised

There's three modules of interest

  • high
  • medium
  • low

These refer to the expected RAM usage of each of these systems at runtime. Please select the style which suits the number of blogs you have the most. Do note that this crate is not intended to handle literally millions of

high uses the most RAM by storing the entire blog in memory the whole time, the best way to do this is using a lazy static like so

lazy_static! {
    pub static ref STATIC_BLOG_ENTRIES: HighBlog =
        get_high_blog(PathBuf::from(BLOG_ROOT), None, None, URL, &SitemapOptions::default());
    }

medium stores the majority of the blog, but not the rendered HTML of the blog posts themselves. These will need to be rendered when requested

lazy_static! {
    pub static ref STATIC_BLOG_ENTRIES: MediumBlog =
        get_medium_blog(PathBuf::from(BLOG_ROOT), None, None, URL, &SitemapOptions::default());
    }

let this_blog = match all_blogs.hash.get(&complete_slug) {
    Some(x) => x,
    None => return None,
};

context.insert(
    "blog",
    &this_blog
        .render(PathBuf::from_str(BLOG_ROOT).unwrap())
        .unwrap(),
);

Finally, low stores absolutely nothing and is intended to be used to get everything at runtime.

let preview = preview_blogs(PathBuf::from_str(BLOG_ROOT).unwrap(), 2, None);
let tags = get_blog_tag_list(PathBuf::from_str(BLOG_ROOT).unwrap());
let blog_post = render_blog_post(PathBuf::from_str(BLOG_ROOT).unwrap(), date, slug, None).unwrap();
let sitemap = create_sitemap(BLOG_ROOT, URL, &SitemapOptions::default());

This method can have serious runtime performance implecations, but might be necessary if the blog can't fit into memory

Examples

This crate comes with three examples - an identical blog website using rocket and tera templates - one using each of the modules. You can run them with

cargo run --example high
cargo run --example medium
cargo run --example low

You can then view them from localhost:8080

Todo

  • More enlightening error messages and generally better error handling
  • This crate is in desperate need of more testing and feedback!
