sql-formatter VS prettierd

To be honest I didn't put much thought into the formatting at all - I went with the defaults for the https://github.com/zeroturnaround/sql-formatter library, which is what runs when you click the "Format SQL" button on this page.

https://github.com/zeroturnaround/sql-formatter is written in JS, might be pretty straightforward to integrate into Code...

First, you need prettierd:

Besides remapping keys, auto-format with prettier (null-ls, ALE, etc) will wrap your code on line break. This might not be desirable for txt files, but it's transparent and fully supported by markdown. It'll also fix things like aligning your markdown tables. There's also prettierd and prettier_d_slim to keep it running as a daemon in the background, which makes the buffer reformatting really snappy.

For react you will need the one for typescript and the eslint lsp is also used in the config to auto fix errors on save. Also this relies on prettierd to be installed globally: https://github.com/fsouza/prettierd

But today I discovered this tool: https://github.com/fsouza/prettierd. This completely solves the issue: the slowness of prettier is due to the overhead of launching the program. This package leaves prettier running as a daemon, which removes the launch overhead (kind of similar to the already famous `eslint_d`).
