Import OPML files into Spotify Podcasts, poorly

opml-to-spotify's Issues

Log missed shows to file

When shows aren't found, add the option to log to a file for manual processing

Doesn't work with OPML file exported from Pocket Casts

Version 1.0.2 on Windows 11

Export from Spotify worked but import doesn't, OPML imports fine into another podcast client on Windows (Grover Podcast) and exporting back out from Grover then using that for opml-to-spotify works

Implement PKCE

Let's look at authorisation code flow with PKCE instead https://developer.spotify.com/documentation/general/guides/authorization/code-flow/

Originally posted by @elliotwms in #4 (comment)

Add `export` command

Give users a way to export their subscribed shows from Spotify as an OPML file

Flow

sequenceDiagram
  opml-to-spotify ->>+ Spotify: GET https://api.spotify.com/v1/me/shows
  Spotify ->>- opml-to-spotify: User's shows
  loop Each show
    opml-to-spotify ->>+ iTunes Search: GET https://itunes.apple.com/search?term={title}&media=podcast&entity=podcast&attribute=titleTerm
    iTunes Search ->>- opml-to-spotify: Podcast (contains feedURL)
    opml-to-spotify ->>+ RSS: GET {feedUrl}
    RSS ->>- opml-to-spotify: Full show details
  end

  • Note: 20/min rate limit

Submit to Spotify

In order for the opml-to-spotify cli to be used without providing a development client ID (and the user making their own Spotify application etc etc), we must submit a quota extension request to Spotify to make the opml-to-spotify application available for general use. This allows users to use the baked-in-at-build time client ID in the background to achieve the sign in flow.

Todo Prep

• Open up access to test users in development
• Gather test user experience data
• Finalise scopes
  • user-library-read to export user's current shows
  • user-library-modify to import (save) shows
• Submit quota extension request

Allow importing more than 50 podcasts

SaveShowsForCurrentUser only allows a maximum of 50 IDs to be passed at any given time. If more than 50 shows are to be imported then we should split up these calls into chunks

Post-v1 actions

• Protect main branch
• Binary signing?

Add tests

Add some sort of testing to satisfy at least a basic CI pipeline

• Build & test
• Lint

Implement implicit grant flow

As the application is short-running, there's no need for a full authorisation code flow.

Implementing the implicit grant flow removes the requirement for a client-side secret, which means we can bundle the client ID into the application, and there's no need for users to create their own Spotify app

## Requirements

• Implement the implicit grant flow
• Bundle the opml-to-spotify application client ID into the build (nice to have if Spotify approve the application)
• Update the docs

Add interactive mode

Allow the user to confirm shows before importing, and select from a list when multiple matches are present

Migrate to goreleaser

Primary concerns:

• More straightforward cross-compilation
• Artifact signing
