Clone the repo\n2. Execute `npm install`\n3. Create a new app / client id at [developer.spotify.com](https://developer.spotify.com/dashboard/applications).\n4. Copy your client id into `/src/config.ts`.\n5. Click \"Edit Settings\" in the newly created Spotify developer app and add a redirect URI to where `/spotify-authorization` will be hosted - by default this will be `https://localhost:3000/spotify-authorization`\n6. Set `HTTPS=true` (HTTPS is required to use `window.crypto`)\n   - In PowerShell: `$env:HTTPS = \"true\"`\n7. Set `NODE_OPTIONS=--openssl-legacy-provider` (react-scripts doesn't play nice with newer versions of Node)\n   - In PowerShell: ` $env:NODE_OPTIONS = \"--openssl-legacy-provider\"`\n8. Execute `npm start`\n9. Accept the SSL warning\n\n## 📷 Snippets From the Web App\n\nExample Sort Visualisation of a Personal Playlist\n![Example Sort Visualisation of a Personal Playlist](https://nitratine.net/posts/emotionify/emotionify-sort-comparison.png)\n\nExample Comparison Visualisation of a Personal Playlists\n![Example Comparison Visualisation of a Personal Playlists](https://nitratine.net/posts/emotionify/emotionify-compare-box-plot.png)\n\nExample of Applying Filters to Playlists\n![Example of Applying Filters to Playlists](https://nitratine.net/posts/emotionify/emotionifytools-page-demo.png)\n\n## 📝 Features\n\n- **Spotify authorization for library access**\n- **Sort a playlist by valence and energy** - Sorting on these two values can create a transition from sadder/slower songs to more happy/energetic songs. - Can change the sorting audio features and sorting method - Exports to a new playlist\n- **Compare playlists** - Compare multiple playlists in 1D, 2D or 7D from selected audio features.\n- **Playlist tools** - Add playlists and apply filters and functions to playlists to manipulate song ordering - Exports to a new playlist\n\n\u003e All [audio features](https://developer.spotify.com/documentation/web-api/reference/tracks/get-audio-features/) used are pre-computed by Spotify and obtained through their API.\n\n## ❓ Why?\n\nEmotionify is an application I had thought about for a few years after doing a project at university on attempting to detect emotion in music and portraying it in an interactive environment.\n\nI was curious how the method implemented would play out with music I listen to every day and wanted some extra tools for Spotify playlists.\n\nEmotionify is not 100% accurate as emotion is highly opinion based and the values used to sort songs are averages over the whole song. This tool however does give insight on how well a computer can plot an emotional gradient with a list of songs.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbrentvollebregt%2Femotionify","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbrentvollebregt%2Femotionify","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbrentvollebregt%2Femotionify/lists"}
