There are 3 possibilities to install the frontend: 1. invoke frontend-download --ref 01f2aa5f746a36706e9a5e588c4242b7bf1996d5 if ref is omitted, it tries to auto detect the current git ref via `git rev-parse HEAD`. Note: GitHub doesn't allow workflow artifacts to be downloaded from anonymous users, so this will output a link where you can download the frontend with a signed in browser and then continue with option 3 2. invoke frontend-download --tag 0.13.0 Downloads the frontend build from the releases. 3. invoke frontend-download --file /home/vscode/Downloads/frontend-build.zip This will extract your zip file and place the contents at the correct destination """ import functools import subprocess from tempfile import NamedTemporaryFile from zipfile import ZipFile import requests print('Downloading frontend...') # globals default_headers = {'Accept': 'application/vnd.github.v3+json'} # helper functions def find_resource(resource, key, value): for obj in resource: if obj[key] == value: return obj return None def handle_extract(file): # if no extract is requested, exit here if not extract: return dest_path = Path(__file__).parent / 'src/backend' / 'InvenTree/web/static/web' # if clean, delete static/web directory if clean: shutil.rmtree(dest_path, ignore_errors=True) os.makedirs(dest_path) print(f'Cleaned directory: {dest_path}') # unzip build to static folder with ZipFile(file, 'r') as zip_ref: zip_ref.extractall(dest_path) print(f'Unzipped downloaded frontend build to: {dest_path}') def handle_download(url): # download frontend-build.zip to temporary file with requests.get( url, headers=default_headers, stream=True, allow_redirects=True ) as response, NamedTemporaryFile(suffix='.zip') as dst: response.raise_for_status() # auto decode the gzipped raw data response.raw.read = functools.partial( response.raw.read, decode_content=True ) with open(dst.name, 'wb') as f: shutil.copyfileobj(response.raw, f) print(f'Downloaded frontend build to temporary file: {dst.name}') handle_extract(dst.name) # if zip file is specified, try to extract it directly if file: handle_extract(file) return # check arguments if ref is not None and tag is not None: print('[ERROR] Do not set ref and tag.') return if ref is None and tag is None: try: ref = subprocess.check_output( ['git', 'rev-parse', 'HEAD'], encoding='utf-8' ).strip() except Exception: print("[ERROR] Cannot get current ref via 'git rev-parse HEAD'") return if ref is None and tag is None: print('[ERROR] Either ref or tag needs to be set.') if tag: tag = tag.lstrip('v') try: handle_download( f'https://github.com/{repo}/releases/download/{tag}/frontend-build.zip' ) except Exception as e: if not isinstance(e, requests.HTTPError): raise e print( f"""[ERROR] An Error occurred.
