is-webgl-build

Validates if given folder is a valid WebGL build folder

validates WebGL builds exported from Unity

Note:

• Currently only WebGL builds are supported. Contributions are encouraged!.
• Ensure that the file names referenced in index.html inside the build folder match the actual file names.
• Exact content validation is quite tricky, so for that purpose,consider using http-server module or any other http-server to check for runtime issues.
• This package primarily validates structure, checking for corrupted files(size 0) & detect missing files

Features

• Validate WebGL builds (works for compressed as well as uncompressed builds)
• Detect missing or malformed files
