A parser for Nodejs that converts osu files into javascript objects. Feel free to give it a try and post issues to help me improve it ;)
npm install osu-parser
var parser = require('osu-parser');
parser.parseFile('path/to/map.osu', function (err, beatmap) {
console.log(beatmap);
});Simple key/value entries like this...
...
PreviewTime: 42860
...
...are directly reachable as properties :
console.log(beatmap['PreviewTime']);
// prints 42860
| name | type | description |

| fileFormat | String | osu file format (v7, v12...). |
| bgFilename | String | name of the background image. |
| nbCircles | Integer | number of circles. |
| nbSliders | Integer | number of sliders. |
| nbSpinners | Integer | number of spinners. |
| bpmMin | Integer | minimum bpm. |
| bpmMax | Integer | maximum bpm. |
| maxCombo | Integer | maximum combo. |
| totalTime | Integer | total time in seconds. |
| drainingTime | Integer | draining time in seconds. |
| tagsArray | Array | tags splitted into an array, for convenience. |
| breakTimes | Array | list of all break times. Each has startTime and endTime properties. |
| timingPoints | Array | list of all timing points. See TimingPoint below. |
| hitObjects | Array | list of all hitobjects. See HitObject below. |
| name | type | description |
|---|---|---|
| offset | Integer | offset in milliseconds. |
| beatLength | Float | length of a single beat in milliseconds. Inherited from previous timing point if negative. |
| bpm | Float | number of beats per minute. Inherited from previous timing point if beatLength is negative. |
| velocity | Float | velocity multiplicator. |
| timingSignature | Integer | 3 = simple triple, 4 = simple quadruple (used in editor). |
| sampleSetId | Integer | sound samples. None = 0, Normal = 1, Soft = 2. |
| customSampleIndex | Integer | index of the custom sound samples. (0 if none) |
| sampleVolume | Integer | volume of the samples. |
| timingChange | Boolean | is there a beatLength change ? |
| kiaiTimeActive | Boolean | is it a kiai section ? |
| name | type | description |
|---|---|---|
| objectName | String | circle, slider, spinner or unknown. |
| position | Array[Integer] | object position : [x,y] |
| startTime | Integer | start offset. |
| newCombo | Boolean | is it a new combo ? |
| soundTypes | Array | list of sound effects. Those can be : normal, whistle, finish, clap. |
| additions | Object |
hitobject specific additions. It can have those properties :
- sample: object specific sample. It can be : soft, normal, drum.
- additionalSample: the sample to use for additional sounds (finish, whistle, clap). It can be : soft, normal, drum.
- customSampleIndex: index of the custom sample to use (ex: normal-2).
- hitsoundVolume: specific volume for this object (require hitsound to be an existing file).
- hitsound: a file to use as hitsound. It disables all other hitsounds.

| name | type | description |
|---|---|---|
| repeatCount | Integer | number of repeats, starts at 1 for a single-way slider. |
| pixelLength | Integer | length in osu-relative pixels. |
| duration | Integer | duration in milliseconds, rounded to the upper integer. |
| endTime | Integer | end offset. |
| curveType | String | can be catmull, bezier, linear or pass-through. |
| points | Array | list of all points including the very first. Each point is an array of coordinates [x,y]. |
| endPosition | Array | coordinates of the slider end ([x,y]). (not calculated for catmull) |
| edges | Array |
list of edges. The number of edges is repeatCount + 1. Each one has two properties :
- soundTypes: list of sound effects. Those can be : normal, whistle, finish, clap.
- additions: edge additions. Same as hitobject additions, but can only have sample and additionalSample.

Parse the given file. The callback returns (error, beatmap).
var parser = require('osu-parser');
parser.parseFile('path/to/map.osu', function (err, beatmap) {
console.log(beatmap);
});Parse a stream containing a file content. The callback returns (error, beatmap).
var parser = require('osu-parser');
var fs = require('fs');
var stream = fs.createReadStream('path/to/map.osu');
parser.parseStream(stream, function (err, beatmap) {
console.log(beatmap);
});Parse the content of a file as a string or a buffer.
var parser = require('osu-parser');
var fs = require('fs');
var content = fs.readFileSync('path/to/map.osu');
var beatmap = parser.parseContent(content);- translate the samplesetId of timing points
- parse events
- make tests more reliable
- add a synchronous version of parseFile
- make it usable in a browser ? (not sure that would be useful)
