Subject of the issue

Every recompile takes 50 seconds (cargo build --features sqlite) , so every time I change the code, even if it's only one file, I have to wait 50s to preview it, Is it normal to consume this time?
BTW, the cargo's incremental build look like work.
Is there a better(fast) development way? (i'm a javascript coder, i don't have compiled language work experience)

Your environment

MacOS, 10.15.3

Bitwarden_rs version:
v1.13.1

Steps to reproduce

cargo build --features sqlite
......
Finished dev [unoptimized + debuginfo] target(s) in 53.89s

Yes, building rust code is slow. If you only want to check if the code compiles and not actually run it, you can use cargo check --features sqlite, which should be considerably faster.

Does this mean that if I modify a api or view, I have to wait 50 seconds before actually preview it on the browser? (cargo run --features sqlite)

After I modify the code, I hope to preview it on the client. Is there any way to make code changes work faster?

If you modify the API, yes you'd have to wait and there's no faster way.

If you change the HTML templates, you can enable the following options:

TEMPLATES_FOLDER=src/static/templates
RELOAD_TEMPLATES=true

and with that any changes to the templates are applied immediately (for emails they apply to the next ones sent, for the admin page, after a page reload).
