Lexicons Source Architecture

[irina060981]

Current workflow to get lexicons:

• accoding to the dictionary we get an url with the list of all words,
  for example, for Latin https://repos1.alpheios.net/lexdata/ls/dat/lat-ls-ids.dat (980 kb)
• parse the file with paparse library to the Dictionary
• cache all the Dictionary to module's closure variable
• search for the word

if it already has cached dictionary it simply searched in it.
So we could see the following disadvantages:

1. parsing, fetching data from the whole amount of data on the client side
2. we need to store the all definitions inside RAM

I suggest to look for a new workflow of retrieving this data - from structured database on the server - for example the easiest way - SQLite. It could be used on the server and for the local use.
