# Anyd
Anyd is a small framework that will help you build and use *any* custom Unix *daemon* process as a server. It will suite your daemon with API accessible over sockets, so you'll be able to query it for runnig your code or transmit the data. Anyd provides you a client out-of-the-box, so you can start working with your daemon instantly.
# How-to
Anyd provides you an app to start with:
```python
from anyd import Appd
```
Define the address for your daemon, for example:
```python
address = ("localhost", 3000)
```
The daemon process will use it to accept connections. Next, create a daemon app:
```python
appd = Appd(address)
```
Or you can set it up with authentication for client:
```python
appd = Appd(address, authkey=b"swordfish")
```
Now, define your API endpoints, using `@appd.api`:
```python
@appd.api
def echo(arg: str) -> str:
return arg
```
Additionally, you can use built-in logger to log something specific:
```python
from anyd import logging
@appd.api
def echo(arg: str) -> str:
logging.info(f"echoing: {arg}")
return arg
```
This function is now exposed to the client as an API endpoint, and can be executed on request.
You are ready to start the deamon:
```python
appd.start()
```
That will block the interpreter and you'll see the logging output of your daemon in the terminal:
```
[INFO] Listening on 127.0.0.1:3000
```
Let's test it from another shell!
Start from importing `ClientSession`:
```python
from anyd import ClientSession
```
Use it with address and authkey you used for your daemon:
```python
address = ('localhost', 3000)
with ClientSession(address, authkey=b"swordfish") as client:
# you can pass keyword arguments to API request
response = client.commit("echo", arg="hello world!")
# or the positional ones
bob = client.commit("echo", "hello Bob")
# you can query different API endpoints per-session
try:
# Will raise NotImplementedError:
# we didn't defined 'my_func' endpoint on the daemon.
# The daemon will continue working.
client.commit("my_func", "hello")
except NotImplementedError as ex:
print(ex) # NotImplementedError: my_func
print(response) # hello world!
print(bob) # hello Bob
```
## Validators
On the daemon app you may want to define sort of validation logic for some of your endpoints. In this case, you can return an exception as a response to the client. It will be pickled and raised on the client side, so your daemon will stay up and running. Consider simple example with previous endpoit:
```python
def validate_echo(arg: Any):
if not isinstance(arg, str):
return TypeError(f"{arg}, {type(arg)}")
return arg
@appd.api
def echo(arg: str) -> str:
return validate_echo(arg)
```
The function `validate_echo` is not an API endpoint of our daemon, but still its accessible for the daemon to execute it locally.
Now, let's try to query it with wrong data:
```python
with ClientSession(address) as client:
try:
client.commit("echo", 1) # will raise TypeError
except TypeError as ex:
print(ex) # 1, <class 'int'>
```
# Features
- Get to your server's functionality implementation instantly
- Don't bother with a low-level sockets programming
- The client for your server comes out of the box and is ready to use
# Installation
Install it by running:
```
pip install anyd
```
