168 | and charge a fee for, acceptance of support, warranty, indemnity,
169 | or other liability obligations and/or rights consistent with this
170 | License. However, in accepting such obligations, You may act only
171 | on Your own behalf and on Your sole responsibility, not on behalf
172 | of any other Contributor, and only if You agree to indemnify,
173 | defend, and hold each Contributor harmless for any liability
174 | incurred by, or claims asserted against, such Contributor by reason
175 | of your accepting any such warranty or additional liability.

1 | ## Unofficial recent changes lister for Notion.so sites
2 |
3 | Notion.so is a nice document database, but its notifications system is very
4 | bad:
5 |
6 | - By default it only shows you pages you've subscribed to.
7 |
8 | - If you subscribe to too many pages, or look at the "All" tab, the list of
9 | changes is very cluttered.
10 |
11 | - If someone works all day making 100 changes to a single page, and five
12 | other pages get one simple change each during the day, the 100
13 | notifications drown out the five notifications so you'll never see them.
14 |
15 | - The change view is in a tiny box that doesn't make full use of your
16 | browser window.
17 |
18 | - It's hard to tell which changes you have or haven't already looked at.
19 |
20 | - It's hard to tell which pages have changed recently and which haven't.
21 |
22 | This app, which uses the "unofficial" Notion.so api client from
23 | https://github.com/kjk/notionapi, tries to resolve all these issues in the
24 | simplest possible way:
25 |
26 | - In a single view, it shows each (somewhat recently modified) page in your
27 | notion database exactly once, along with who edited it most recently and
28 | which day it was edited.
29 |
30 | - Each page link contains a revision indicator so that your browser can tell
31 | if you've visited that revision before or not. The link colour changes if
32 | you have. This makes it easy to tell, at a glance, which revisions you've
33 | read or not read, and which things have changed since the last time you
34 | opened a page.
35 |
36 | - It's a totally dumb, flat, no-javascript html view that expands to fill
37 | the space available on your screen, and loads very fast.
38 |
39 | - That's it!
40 |
41 |
42 | ## Configuring notionchanges
43 |
44 | You need to provide two files, which must be in the current working
45 | directory at the time you start the `notionchanges` binary:
46 |
47 | - `notion.key`: a text file containing the `token_v2` cookie extracted from
48 | your notion session. The app uses this to access the notion API using your
49 | personal rights. You might need to refresh this file occasionally if you
50 | get logged out.
51 |
52 | - `space.id`: a text file containing the notion id of the "space" that forms the root of your
53 | notion database. You can find this by using Chrome's debugger to inspect
54 | the response to a `loadPageChunk` command in notion. (It generates at
55 | least one of these every time you load notion.) Look inside the returned
56 | `recordMap` object, then in the `space` object, and copy the uuid in
57 | there. [TODO: if none is configured, offer a list of spaces to choose
58 | from.]
59 |
60 |
61 | ## Running notionchanges
62 |
63 | To run the program, use these steps:
64 |
65 | - `git clone https://github.com/apenwarr/notionchanges`
66 | - `go run .`
67 | - Visit http://localhost:8187/
68 |
69 |
70 | ## How do I control which users can see the page?
71 |
72 | It's not a good idea to publish the notionchanges view directly on the
73 | Internet, since it has no authentication. You can put it behind a proxy or
74 | control access using a VPN such as [Tailscale](https://tailscale.com/).
75 |
76 |
77 | ## How can I contribute?
78 |
79 | There are surely many ways to improve this project.
80 |
81 | Unfortunately I don't have time to fix most bugs or add new features. Sorry!
82 | But you can fork this repo and submit pull requests and I'll do my best to
83 | look at them and merge them if they're a good fit.
