⚠ Doesn't work for patch 14.1 and onwards, working to fix it, see Issue 25
Neeko-Server is an application that record games emulates a League of Legends spectator server to serve them to the League of Legends client.
It is an asynchronous software capable of recording multiple League of Legends live games at the same time, while simultaneously allowing multiple League of Legends clients to watch different games at the same time.

}This application uses the Riot Games API to get the gameId of a summoner currently in game, in order to record that game.
If config.spectator.get_riot_match_details is set to true, it will also query for the results of the game through the match endpoint of the Riot Games API.
Thus, if you want to fully use this application your API key must have access to the corresponding endpoints:
/lol/summoner/v4/summoners/by-name/{summonerName}
/lol/spectator/v4/active-games/by-summoner/{encryptedSummonerId}
/lol/match/v5/matches/{matchId}
If you just want to serve games you already recorded, the API key is not necessary.
Record the live game of a riot account. The region options are:
BR1, EUN1, EUW1, KR, LA1, LA2, NA1, OC1, TR1, RU, JP1 and PBE1
The gameName and tagLine options are depends of the target riot account. For Vivi#EUW the gameName is Vivi and the tagLine is EUW.
Additionally, you can specify a secret in config.server.secret.spectate_secret, and if config.server.secret.check_spectate_secret is enabled, the request will not go through unless you have a Secret header which value matches with config.server.secret.spectate_secret.
When recording a game that has already started, you may see a lots of chunks unavailables messages on the console. These are not errors, it is just impossible to get the past data of a game, only the data from the moment you started spectating.
As with the endpoint above, you can secure this one using config.server.secret.statistics_secret
It provides statistics, mainly the list of the games that are currently being recorded, and those which are already saved. One interesting thing about this endpoint is that you can specify custom game data if you enabled the config.spectator.get_riot_match_details endpoint. You just need to edit the getCustomGameStats function, located in the src/utils/getCustomGameStats.ts file. I set it to output the largest multi kill in a match, and its duration in minutes as an example.
Here is an example response:
{
"spectators": [ // Spectators client, one for each game currently being recorded
{
"gameId": 1234567890,
"region": "EUW1",
"targetSummonerName": "Player 1",
"date": "Mar 6, 2022 2:13:19 PM",
"liveGameMinutes": 17,
"interestScore": 1932
}
],
"games": [ // Games stored on the spectator server
{
"gameId": 1234567891,
"region": "EUW1",
"targetSummonerName": "Player 2",
"date": "Mar 6, 2022 12:27:03 PM",
"interestScore": 1097,
"gameLength": 0,
"gameMode": "CLASSIC",
"gameType": "MATCHED_GAME",
"custom": {
"largestMultiKill": 3,
"gameMinutes": 21
}
}
]
}Download a .bat file that will launch the League of Legends client to spectate the specified game ID on our spectator server. The corresponding game must have been recorded previously using the application.
Feel free to propose any PR, they are very welcome especially on the fastify error code management (errors getting caught inside the router functions) and on the architecture of the project.
Special thank to the loldevs team for their work on reversing the League of Legends spectator servers nearly a decade ago (https://github.com/loldevs/leaguespec) and more so to Divi for his past implementation of a spectator server (https://github.com/EloGank/lol-replay-downloader) that inspired me for the getLastChunkInfo endpoint implementation.
