A nice last minute sanity check I use is a `pre-commit` hook that auto runs test and lint commands from a `makefile` or 
`package.json` if they're found:

```bash
#!/usr/bin/env bash

if [ -f "$PWD/makefile" ] && [ ! -z "$(cat $PWD/makefile | grep '^lint:')" ]; then
    echo "running make lint"
    make lint
elif [ -f "$PWD/package.json" ] && [ ! -z "$(cat $PWD/package.json | grep "^\"lint\":")" ]; then
    echo "running npm run lint"
    npm run lint
fi

if [ -f "$PWD/makefile" ] && [ ! -z "$(cat $PWD/makefile | grep '^test:')" ]; then
    echo "running make test"
    make test
elif [ -f "$PWD/package.json" ] && [ ! -z "$(cat $PWD/package.json | grep "^\"test\":")" ]; then
    echo "running npm run test"
    npm run test
fi
```

If the test or lint command fails then the `git commit` command fails. If I absolutely need to commit something in spite
of the lint/test results I can do `git commit --no-verify` to skip the `pre-commit` hook.
