All Clear Ahead, Captain.

Flow & Vue

Shrimpit supports Flow annotations and Vue templates out of the box!

TypeScript (experimental)

Since Babel 7, the TypeScript AST can directly be parsed. You can use the --typescript flag to enable it:

shrimpit --tree --typescript path/to/your/files

Please note that the Flow and TypeScript parsers are mutually exclusive.

Linting

The code quality is checked by the JavaScript Standard Style.
