git-spawned-stream

Create a readable stream from a spawned git process.

Usage

gitSpawnedStream(repoPath, spawnArguments, limitInBytes, gitBinary)

Arguments:

• repoPath - the path to the repo, ex: /home/alex/node/.git (or the path to the git bare repo)
• spawnArguments - the arguments that will be passed to the child_process.spawn function
• limitInBytes - kill the process if it exceeds the imposed limit (sends more data than allowed)
• gitBinary - path to the git binary to use (use the one in PATH by default)

Example:

var gitSpawnedStream = require('git-spawned-stream');
var path = require('path');
var repoPath = process.env.REPO || path.join(__dirname, '.git');
repoPath = path.resolve(repoPath);
var byteLimit = 5 * 1024 * 1024; // 5 Mb

// sort of a git log -n 2
var stream = gitSpawnedStream(repoPath, [
  'rev-list',
  '--max-count=2',
  '--header',
  'HEAD'
], byteLimit);

stream.on('data', function(data) {
  console.log('DATA', data.toString('utf8'));
}).on('error', function(err) {
  console.error('An error occurred:');
  console.error('-----------------\n');
  console.error(err.message);
  process.exit(1);
}).on('end', function(killed) {
  // when the stream is cut, killed === true
  console.log("\n±±±±±±±±±±±±±±±±±\nThat's all folks!");
});
