-This is the code repo of my [personal website](https://lumither.com),

-- [ ] the todo list lol
+This is an example of [db repo](https://github.com/Lumither/blog-posts.git).
-- [ ] and much more...

+        {
+            "type": "dir",
+            "name": "posts"
+        }
+    ]
+}
+master > cat ./posts/idx.json
+{
+    "idx": [
+        {
+            "type": "md",
+            "name": "another_article.md",
+            "meta": {
+                "title": "another_article!",
+                "desc": "test",
+                "tag": ["blog", "test", "dev"]
+            }
+        },
+        {
+            "type": "md",
+            "name": "hello_world.md",
+            "meta": {
+                "title": "Hello World!",
+                "desc": "test",
+                "tag": ["blog", "test", "dev"]
+            }
+        }
+    ]
+}
+```
+
+These are examples of `idx.json`. They were designed to be placed at any layer of the directory, and used
+to accelerate the client side browsing. The following is an easy [implementation](/app/blog/fetch_posts.ts) of using `idx.json` at `/posts` 
+to get a list of blog posts.
+
+```ts
+export default async function fetch_posts(url: string): Promise<Result<JSON[], Error>> {
+    const response = await fetch(`${ url }/posts/idx.json`);
+    if (!response.ok) {
+        return {
+            ok: false,
+            error: new Error(response.statusText)
+        };
+    }
+    const res = await response.json();
+    const posts = res['idx'].filter((posts: { type: string }) => posts.type === 'md');
+    return {
+        ok: true,
+        value: posts
+    };
+}
+```
+
+The approach work impressively well, thanks for the globe services of GitHub lol, but eventually the plan was changed
+due to ethical reasons and possibility of breaking GitHub's EULA. Plus, the functionality of the blog site might be constrained due to
+Cloudflare worker's CPU time limitations, considering the existence of potential resource-intense work such as on-site searching and analytics.

-- Will render to `https://<DOMAIN>/blog/post/<identifier>`.
-- Files under `assets/` (where images etc. located) should be pushed to OSS.
-- For identifiers, use prefix `-` to indicate private (hidden) visibility. EX: `-hello-world`.
