This regex can be used on a JavaScript/TypeScript file to find imports from third-party packages. This is useful for determining what to put in dependencies/peerDependencies. This is a Rust regex, which makes it easy to use with rg (ripgrep). Pro tip: combine rg with sort -u to get a list of all packages for your JS/TS project! Based on a similar PCE2 regex

AWS EventBridge Scheduling Expressions

Java
This validates AWS EventBridge scheduling expressions using the rate() and cron() formats. It may not catch all invalid expressions, but it should properly validate all valid expressions, as demonstrated in the unit tests. Please let me know if I missed any valid expressions. Originally attempted this using named capture groups and named back-references to reduce duplication. Unfortunately, named capture support is tricky, so they were all converted to duplicated non-capturing groups instead.
