Prep for 2.2.0 (#210)
Browse files Browse the repository at this point in the history
* added rapidapi key integration

* prep for 2.1.3

* Removing get_batch_stock_quotes method (#189)

* Removing get_batch_stock_quotes method

Remove get_batch_stock_quotes method, resolving issue #184.

* remove tests for get_batch_stock_quotes

* Delete mock_batch_quotes

Was only used for the tests removed in the previous commits, which made this file dead weight.

* Add asyncio support for all components (#191)

* Add asyncio support for all components

In order to minimize the copy-paste between the async and sync
implementations, all of the non-base components are sym-linked to their
sync counterparts.  Since these import `AlphaVantage` locally, they
automatically pick up the async version, which is really nifty!

There was some refactoring in `SectorPerformance` to make the re-use
possible.

The async verison of AlphaVantage tries to re-use as much as possible
from the sync version.  The main differences are:
* a new `session` for the HTTP calls
* a new `close()` function which should be called when you're done
* `proxy` is a string instead of a dict

Using it:
```python
import asyncio
from alpha_vantage.async_support.timeseries import TimeSeries

async def get_data():
    ts = TimeSeries(key='YOUR_API_KEY')
    data, meta_data = await ts.get_intraday('GOOGL')
    await ts.close()

loop = asyncio.get_event_loop()
loop.run_until_complete(get_data())
loop.close()
```

* Add asyncio packages to setup.py

* Issue #206: Add 'time_period' argument to 'get_bbands()' documentation. (#207)

* Fixes small documentation bugs (#208)

* fixed fx documentation

* fixed pypi badge for documentation

* prep for 2.2.0 (#209)

* fixed fx documentation

* fixed pypi badge for documentation

* prep for 2.2.0

* small documentaiton change for 2.2.0

* From version 2.2.0 onwards, asyncio support now provided. See below for more information.
* From version 2.1.3 onwards, [rapidAPI](https://rapidapi.com/alphavantage/api/alpha-vantage-alpha-vantage-default) key integration is now available.
* From version 2.1.0 onwards, error logging of bad API calls has been made more apparent.
* From version 1.9.0 onwards, the urllib was substituted by pythons request library that is thread safe. If you have any error, post an issue.

### Asyncio support

From version 2.2.0 on, asyncio support will now be available. This is only for python versions 3.5+. If you do not have 3.5+, the code will break.

The syntax is simple, just mark your methods with the `async` keyword, and use the `await` keyword.

Here is an example of a for loop for getting multiple symbols asyncronously. This greatly improving the performance of a program with multiple API calls.

```python
import asyncio
from alpha_vantage.async_support.timeseries import TimeSeries

symbols = ['AAPL', 'GOOG', 'TSLA', 'MSFT']


async def get_data(symbol):
ts = TimeSeries(key='YOUR_KEY_HERE')
data, _ = await ts.get_quote_endpoint(symbol)
await ts.close()
return data

loop = asyncio.get_event_loop()
tasks = [get_data(symbol) for symbol in symbols]
group1 = asyncio.gather(*tasks)
results = loop.run_until_complete(group1)
loop.close()
print(results)
```
