readme-as-a-function

Graphql api as a function, runs in openfaas.

Allows you to fetch the n last readmes. Also possible to filter based on year and issue number.

Storage format

The readmes are stored in a bucket in the following format:

# The bucket has two top-level directories:
/images/
# and
/pdf/

# Both these folders follow the schema <year>/<year>-<edition>.<ext>
# So we have the following folders:
/pdf/1994/
/pdf/1995/
#...
/pdf/2020/
# The same goes for images
/images/2020/

# In all the year folders, the pdfs and images are stored:
/pdf/1994/1994-01.pdf
/pdf/1994/1994-02.pdf
# ...and so on
# Again images must follow the same schema
/images/1994/1994-01.jpg

If the bucket does not follow this schema, the api will not give the correct results!

Note also that we do not check the file extension. It's assumed that all files in /pdf/ are .pdf. The api creates a link based on the file, so any files will resolve. For images, any valid file format works, so jpg, png, gif, whatever.
