To start your Phoenix server:
|
|
|
|
- Run `mix setup` to install and setup dependencies
|
|
- Start Phoenix endpoint with `mix phx.server` or inside IEx with `iex -S mix phx.server`
|
|
|
|
Now you can visit [`localhost:4000`](http://localhost:4000) from your browser.
|

## Dev Notes
|
|
|
|
### Search
|
|
|
|
- SQLite supports full-text search via the built-in FTS5 extension, which is enabled by default and loaded in the Elixir Driver.
|
|
The extension requires building a virtual table that holds the data to be searched. This seems to be akin to a materialized view.
|
|
- To have fuzzy search, another extension needs to be loaded.
|
|
[Exqlite](https://github.com/elixir-sqlite/exqlite?tab=readme-ov-file) recommends using [ExSqlean](https://github.com/mindreframer/ex_sqlean),
|
|
which in turn uses [Sqlean](https://github.com/mindreframer/sqlean), but the extension is NOT part of the ExSQlean set.
|
|
Need to investigate with forking and PR.
|
|
|
|
### Queries
|
|
|
|
- To get the count of records per genre:
|
|
|
|
```
|
|
select genre.value, count(genre.value) as c from records, json_each(records.genres) genre group by genre.value order by c desc;
|
|
```
|
|
|
|
- To get the count of records per artist:
|
|
|
|
```
|
|
select json_extract(artist.value, '$.name') AS name, count(1) as c from records, json_each(records.artists) artist group by name order by c desc;
|
|
```
|
|
|
|
Note that this query would fail to disambiguate artists with the same name - can be fixed by using the artist `musicbrainz_id`.
|
|
