dlgit

Download part of a git repository without wasting your bandwidth.

NPM Package | GitHub Repository | Documentation

Why & How

dlgit can download only part of a git repository and reduce the time and bandwidth you spend downloading the whole repository.

dlgit does the followings:

1. serve the files from the local cache if they are available.
2. git clone with optimized options.
   • --filter=blob:none to avoid downloading all file contents.
   • --no-checkout to avoid automatically checking out the files.
   • --depth=1 to avoid downloading history of the repository.
3. setup sparse-checkout to only download the files that are required.
4. git checkout to check out the files you need.
5. remove .git directory to avoid messing up the files.
6. cache the files in the local cache.

Usage

Install Globally

npm i -g dlgit
dlgit --help

# dg --help
# this should work as well since dg is the alias of dlgit

dg --sub /packages/create-vite/template-vue-ts "vitejs/vite#v2.9.9"
# download the files in the subdirectory `packages/create-vite/template-vue-ts` in 
# tag `v2.9.9` of the GitHub repository `vitejs/vite`

Just Run

npx dlgit --sub /public "https://gitlab.noj.tw/noj/codebase/frontend.git#readme"
