hotsparserjs is a node based parser for Heroes of the Storm replay files. The goal of this project is to create a clean, well formatted data structure from replays. The top objectives of this parser are:

• Keep the data structure relevant to actual game information and trim any internal technical information
• Allow conditional parsing of specific data
• Make it easy to extend the parser to more easily support doing any kind of data analysis

Data parsing hotsparserjs is not hard coded. A basic data parsing framework exists in the parser module, and then specific data parsing is implemented in the parsers module. Each parser is implemented via a parser plugin that hooks into events fired from the main loop.

The parser fires the following events that can be intercepted by the plugin:

• parse.start: Signals the start of parsing. Receives all decoded replay data as an argument
• DETAILS: This passes along information decoded from the details portion of the replay
• [.[: Events that are fired from the replay file (see below for examples)
• parse.end: Signals the end of parsing.

The following events are fired in the parsing loop:

• NNet.Replay.Tracker.SPlayerSetupEvent
• NNet.Replay.Tracker.SUnitBornEvent
• NNet.Replay.Tracker.SUpgradeEvent
• NNet.Replay.Tracker.SStatGameEvent
• NNet.Replay.Tracker.SUnitDiedEvent
• NNet.Replay.Tracker.SUnitPositionsEvent
• NNet.Replay.Tracker.SUnitOwnerChangeEvent
• NNet.Replay.Tracker.SUnitRevivedEvent
• NNet.Replay.Tracker.SUnitTypeChangeEvent
• NNet.Replay.Tracker.SScoreResultEvent
• NNet.Game.SBankFileEvent
• NNet.Game.SBankSectionEvent
• NNet.Game.SBankKeyEvent
• NNet.Game.SBankSignatureEvent
• NNet.Game.SUserFinishedLoadingSyncEvent
• NNet.Game.STriggerSoundLengthSyncEvent
• NNet.Game.SUserOptionsEvent
• NNet.Game.SCameraUpdateEvent
• NNet.Game.SSelectionDeltaEvent
• NNet.Game.SCmdEvent
• NNet.Game.SCmdUpdateTargetPointEvent
• NNet.Game.SCommandManagerStateEvent
• NNet.Game.SCmdUpdateTargetUnitEvent
• NNet.Game.SControlGroupUpdateEvent
• NNet.Game.SHeroTalentTreeSelectedEvent
• NNet.Game.STriggerTransmissionOffsetEvent
• NNet.Game.STriggerTransmissionCompleteEvent
• NNet.Game.STriggerDialogControlEvent
• NNet.Game.STriggerSoundOffsetEvent
• NNet.Game.SUnitClickEvent
• NNet.Game.STriggerSoundtrackDoneEvent
• NNet.Game.STriggerPingEvent
• NNet.Game.STriggerCutsceneEndSceneFiredEvent
• NNet.Game.SGameUserLeaveEvent
• NNet.Game.SLoadingProgressMessage
• NNet.Game.SPingMessage
• NNet.Game.SChatMessage

It's very easy to extend the parser to do any sort of analysis upon replays that you want. Simply write a new parser plugin and attach it.
