geit v0.0.7

geit 🐐

Simply get source code trees from a git repository via Smart HTTP.

• No git command-line tool required
• Caching git objects with levelup (Using memdown as a backend by default)
• Supporting HTTP Authentication, proxies, etc. with request

Installation

$ npm install --save geit

Examples

Get 'README.md' on HEAD

const geit = require('geit');
const repo = geit('https://github.com/h2so5/geit.git');

repo.tree('HEAD', function(tree, err) {
  const blobID = tree['README.md'].object;

  repo.blob(blobID, function(data, err) {
    console.log(data.toString());
  });
});

Get 'README.md' on HEAD (Promise)

const geit = require('geit');
const repo = geit('https://github.com/h2so5/geit.git');

repo.tree('HEAD').then((tree) => {
  const blobID = tree['README.md'].object;
  
  return repo.blob(blobID);
}).then((data) => {
  console.log(data.toString());
});

Extract all files in a tree

(Same as git clone --depth 1 without .git directory)

const geit = require('geit');
const path = require('path');
const fs = require('fs');

const repo = geit('https://github.com/h2so5/geit.git');

repo.tree('HEAD', function(tree, err) {
  extractTree(repo, tree, './geit');
});

function extractTree(repo, tree, dir) {
  fs.mkdirSync(dir);
  for (let name in tree) {
    const item = tree[name];
    const pathname = path.join(dir, name);
    switch (item.mode) {
      case '040000':  // directory
        extractTree(repo, item.children, pathname);
        break;
      case '120000':  // symbolic link
        repo.blob(item.object, function(blob, err) {
          fs.linkSync(pathname, blob.toString());
        });

        break;
      case '160000':  // submodule
        fs.mkdirSync(pathname);
        break;
      default:
        const mode = parseInt(item.mode.slice(-4), 8); // permissions
        repo.blob(item.object, function(blob, err) {
          fs.writeFileSync(pathname, blob, { mode: mode });
        });
    }
  }
}

HTTP Authentication

const repo = geit('https://github.com/h2so5/geit.git', {
  request: {
    auth: { user: 'username', pass: 'password' },
  },
});

Use leveldown instead of memdown

$ npm install --save leveldown

const levelup = require('levelup');
const repo = geit('https://github.com/h2so5/geit.git', {
  db: levelup('./geit.db'),
});
