Edit History and Diffs API Guide

This guide documents the current Open Library + Infogami APIs you can use to:

Walk over a user's edits
Fetch a record at a specific revision
Pull revision history for one record
Build before/after diffs for specific edits

It is based on the current server implementation in:

We have three types of components on Open Library:

CSS Components: Components which only require a little bit of CSS. These could have a separate HTML template file in openlibrary/templates if it makes sense to have one, and will usually have a separate .less file in static/css/components. Note the .less file must then be imported from the corresponding page's .less file, E.g. static/css/page-user.less.
JavaScript/JQuery components: These are components which require a small amount of functionality, or are legacy implementations. E.g. the multi-input-autocomplete. These will have a JS file in openlibrary/plugins/openlibrary/js, and an import line in openlibrary/plugins/openlibrary/js/index.js.
Vue components: For new, more interactive components, we prefer to use Vue.js. These components will have a .vue file in openlibrary/components. For more info on Vue, read the README in that directory. E.g: LibraryExplorer.vue

All these components make use of BEM class notation to define the c

Script to convert a normal /type/page to a /type/i18n_page. Assumes the current page is in English, and creates the .en page with the same body.

~80% tested. I used it recently but then made some changes. You should be able to copy and paste it into your terminal, or it'll probably also work as a bookmarklet:

This is a bookmarklet that gives some heuristics for data quality of the books in a search result, author page, or list.

To use, go to this page and copy the bookmarklet! (GitHub won't let me place the bookmarklet here).

Turn on/off all layers

img = gimp.image_list()[0]  # Not sure if this gets the last image or the active image
for layer in img.layers:
    layer.visible = False

Thoughts on OL server-side options from 2021-06-09 call with @jdlrobson

Executing vue template from the python

This is apparently an option! @jdlrobson exploring with PyMiniRacer.

Custom webpack loader to import jsdef function from python files

This is one possibility; it would allow us to keep some of the rendering logic in python, and pull it in from the JavaScript.

Node-based call-out

Note: This is a draft and not well proofread. Likely contains errors.

Things I like:

`instanceof` type guards

class Book { id: string }
class Film { imdbId: string }

Well that was a headache! This is certainly not an elegant solution, but it works. Hopefully someone can use these notes to save themselves a bunch of time.

Known issues:

This does not scale easily to any other library
Requires some internal knowledge of lodash's types library which might break on a lodash update

Add `raw-loader` and `@types/lodash`

npm install --save-dev @types/lodash raw-loader
