# Anthracite
|
||||
A web server written in C++
|
||||
A simple web server written in C++
|
||||
|
||||
## Module-Based Backends
|
||||
Anthracite includes a system for allowing different "backend modules" to handle requests.
|
||||
This allows for anthracite to be extended for additional use-cases. For example, the following
|
||||
backends could be implemented:
|
||||
|
||||
- File: Return files from a directory
|
||||
- Reverse Proxy: Pass the request to another server
|
||||
- Web Framework: Pass the request into an application built on your favorite web framework
|
||||
|
||||
## Building & Debugging
|
||||
|
||||
Once you have the repository cloned, you can run the following command to build Anthracite:
|
||||
|
||||
```shell
|
||||
make build
|
||||
```
|
||||
|
||||
It will create a binary file named `./anthracite`
|
||||
|
||||
To save time, you can use the following command to build and run anthracite on port `8080`:
|
||||
|
||||
```shell
|
||||
make run
|
||||
```
|
||||
|
||||
To save time again, you can use the following command to build and debug anthracite in gdb:
|
||||
|
||||
```shell
|
||||
make debug
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
Run the following commands to serve all files located in `./www/`:
|
||||
|
||||
```shell
|
||||
./anthracite [PORT_NUMBER]
|
||||
```
|
||||
|
||||
## Todo
|
||||
- [x] Serve HTML Pages
|
||||
- [x] Properly parse HTTP requests
|
||||
- [x] Add module-based backend system for handling requests
|
||||
- [ ] Cleanup (this one will never truly be done)
|
||||
- [ ] Proper error handling
|
||||
- [ ] Flesh out module-based backend system for handling requests
|
||||
- [ ] Fix glaring security issues
|
||||
- [ ] Better parsing & response generation
|
||||
- [ ] Faster parsing
|
||||
- [ ] Multithreading
|
||||
- [ ] Speed optimizations such as keepint the most visited html pages in memory
|
||||
- [ ] Cleanup codebase
