All files are fetched on memory. So they are cleaned up automatically when a browser tab is closed. vim.wasm is a Vim fork to run it on browser by compiling it to WebAssembly.

vim.wasm is a Vim compiled to WebAssembly. So Vim is running on your browser and has some limitation.

• Shell commands are not available. So if the Vim plugin uses system() or other stuffs which try to execute shell commands, it does not work.
• The Vim is built with 'normal' feature set configuration. Some functionalities enabled in 'big' or 'huge' feature set are not available. For example, sign, conceal or profile.
• vim.wasm fetches all plugin files before starting Vim. Fetching many files or a large file may slows Vim start up.

• Add -local string option to specify local directory instead of using GitHub API
• Consider symlinks
