# fallbaq

A super simple static file server with a focus on fallback to alternate directories. Written in Rust.

```
fallbaq ./files ./fallback_files /more_fallback_files
```

Pass a number of directories. Files will be loaded starting from the first, and then from following directories if they aren't present. A 404 will be returned if the file is not found in any directory.

Think of it as layering different folders on top of each other.

Change the port:

```
fallbaq ./files -p 1337
fallbaq ./files --port 1337
```

# Example:

```markdown
# ./files

- one.png
- two.png
- bars
  - bar1.png
  - bar2.png

# ./fallback_files

- one.png
- two.png
- three.png
- bars
  - bar3.png
  - foos
    - foo1.png

# /var/www/html

- four.png
- bars
  - bar1_old.png
  - bar2_old.png
```

Running the following command:

```
fallbaq ./files ./fallback_files /var/www/html
```

Will expose a file system that looks like this to requests:
