# collectr: Keep your S3 static files up to date. | ||
|
||
More and more, we find ourselves storing our static website files - CSS, | ||
Javascript, images and more - on [Amazon S3](http://aws.amazon.com/s3/). Some | ||
of us do it because we use services like [Heroku](http://www.heroku.com/) and | ||
don't want to force the static files through our web dynos. Others of us do it | ||
to avoid huge bandwidth costs associated with hosting these on our own servers. | ||
Still others do it to take advantage of the scale and distributed nature of S3. | ||
|
||
However, managing our S3 files can be a pain. Each time we change them we have | ||
to minify and reupload them. We also need to set all the metadata we want: | ||
things like Cache-Control headers. This can be boring and error-prone. collectr | ||
aims to help with that. | ||
|
||
## Using collectr | ||
|
||
collectr is a collection of functions built on top of the | ||
[boto](https://github.com/boto/boto) library. This allows you to plug collectr | ||
into any of your Python code however you see fit. For those who want a 'just | ||
works' solution, however, collectr also comes with an example script that is | ||
perfect for using with any Django project. | ||
|
||
If you want simple, you can use collectr like this: | ||
|
||
import collectr | ||
collectr.update('path/to/static/files', 'bucket-name') | ||
|
||
collectr will scan the directory, minify anything that can be minified using | ||
whatever tools you have on your system, and upload all your files to the | ||
specified S3 bucket. Anything that already existed on S3 will have all of its | ||
metadata persisted. | ||
|
||
Of course, you can have quite a bit more control than that. | ||
|
||
import collectr | ||
statics = collectr.StaticDir('path/to/static/files') | ||
statics.output_directory = 'path/to/other/dir' | ||
statics.minifier = 'yuicompressor' | ||
statics.force_update = True | ||
statics.ignore = ['*.jpg', '*.json'] | ||
statics.update('bucket-name') | ||
statics.metadata = {'Cache-Control': 'max-age=3600'} | ||
|
||
## Features | ||
|
||
- Static file minification. | ||
- Ignore filters. | ||
- Multiple directory management. | ||
- Metadata management. | ||
- Fire-and-forget configuration. | ||
|
||
## Installation | ||
|
||
To install collectr: | ||
|
||
$ pip install collectr | ||
|
||
If you don't have `pip` and can't install it, you should complain to your | ||
sysadmin, and then do: | ||
|
||
$ easy_install collectr | ||
|
||
## Contributing | ||
|
||
collectr welcomes contributions, both bug fixes and new features. Any feature | ||
request should strongly consider the implications for the API. API clarity | ||
is valued above new features, so any feature that complicates the API must add | ||
significant value to the library to be accepted. | ||
|
||
If you want to contribute, do the following: | ||
|
||
1. Check that your idea hasn't already been proposed. Check both open **and | ||
closed** issues on GitHub. | ||
2. Fork the repository on GitHub and make your changes. | ||
3. Where possible, write a test that can reproduce the bug, or that will test | ||
the new feature. | ||
4. Send a Pull Request. Don't forget to add yourself to the AUTHORS file. |
