409dffc8ab refactor(traverse)!: generate_uid return a BoundIdentifier (#6294) 
Closes #5020.

`TraverseCtx::generate_uid` and associated methods return a `BoundIdentifier`, containing both symbol ID and name. This reduces boilerplate code for the caller and avoids and unnecessary lookup to get the name.

Also add a couple of helper methods to `BoundIdentifier` to reduce boilerplate further.

e19deaa102 ci(transformer): move post-transform checker to tasks crate (#6288) 
Move post-transform checker into a `tasks` crate. It doesn't feel like it belongs in `oxc_semantic`. It also feels like too heavy a lump of code to put in `tasks/common`.

5a73a663dc refactor(regular_expression)!: Simplify public APIs (#6262) 
This PR makes 2 changes to improve the existing API that are not very useful.

- Remove `(Literal)Parser` and `FlagsParser` and their ASTs
- Add `with_flags(flags_text)` helper to `ParserOptions`

Here are the details.

> Remove `(Literal)Parser` and `FlagsParser` and their ASTs

Previously, the `oxc_regular_expression` crate exposed 3 parsers.

- `(Literal)Parser`: assumes `/pattern/flags` format
- `PatternParser`: assumes `pattern` part only
- `FlagsParser`: assumes `flags` part only

However, it turns out that in actual usecases, only the `PatternParser` is actually sufficient, as the pattern and flags are validated and sliced in advance on the `oxc_parser` side.

The current usecase for `(Literal)Parser` is mostly for internal testing.

There were also some misuses of `(Literal)Parser` that restore `format!("/{pattern}/{flags}")` back and use `(Literal)Parser`.

Therefore, only `PatternParser` is now published, and unnecessary ASTs have been removed.
(This also obsoletes #5592 .)

> Added `with_flags(flags_text)` helper to `ParserOptions`

Strictly speaking, there was a subtle difference between the "flag" strings that users were aware of and the "mode" recognised by the parser.

Therefore, it was a common mistake to forget to enable `unicode_mode` when using the `v` flag.

With this helper, crate users no longer need to distinguish between flags and modes.

911e4e58ab ci(minifier): minifier benchmark measure only the minifier itself (#6222) 
Minifier benchmark currently includes the time to run parser and semantic as well as the minifier itself. Similar to transformer benchmark, only measure the minifier itself in the benchmark.

This will give us a clearer picture of performance changes, and should also reduce variance in the benchmarks.

900cb46f6c refactor(transformer): convert ModuleImports into common transform (#6186) 
An alternative version of #6177.

Convert `ModuleImports` into a common transform. Works much as before, but it inserts `import` / `require` statements by passing them to `TopLevelStatements` common transform, so they get inserted in one go with any other inserted top-level statements. This avoids shuffling up the `Vec<Statement>` multiple times, which can be slow with large files.

`VarDeclarations` also inserts any declarations via `TopLevelStatements` but runs after `ModuleImports`, so can control whether a `var` statement is inserted before or after `import` statements by inserting it via `VarDeclarations` (to appear after `import` statements) or directly into `TopLevelStatements` (to appear before `import` statements). Insertion order is not actually important, but allows us to match Babel's output and pass its tests.

21b08ba141 refactor(transformer): shared VarDeclarations (#6170) 
First step towards #5049.

Various transforms need to add a `var` statement at top of enclosing statement block.

e.g.:

```js
// Input
a ??= b;
```

```js
// Output
var _a;
(_a = a) !== null && _a !== void 0 ? _a : (a = b);
```

Each of these transforms previously maintained it's own stack and added `var` statements individually.

Share this functionality in a "common" utility transform which maintains a single stack to serve them all.

#### Minor Changes

- Support for a new CLI flag, `--exclude-peers`, added to the `list` and
`why` commands. When `--exclude-peers` is used, peer dependencies are
not printed in the results, but dependencies of peer dependencies are
still scanned
[#&#8203;8506](https://redirect.github.com/pnpm/pnpm/pull/8506).
- Added a new setting to `package.json` at
`pnpm.auditConfig.ignoreGhsas` for ignoring vulnerabilities by their
GHSA code
[#&#8203;6838](https://redirect.github.com/pnpm/pnpm/issues/6838).

    For instance:

    ```json
    {
      "pnpm": {
        "auditConfig": {
          "ignoreGhsas": [
            "GHSA-42xw-2xvc-qx8m",
            "GHSA-4w2v-q235-vp99",
            "GHSA-cph5-m8f7-6c5x",
            "GHSA-vh95-rmgr-6w4m"
          ]
        }
      }
    }
    ```

#### Patch Changes

-   Throw an exception if pnpm switches to the same version of itself.
-   Reduce memory usage during peer dependencies resolution.

bfd19882b0 fix(transformer/react): should not collect use-hooks if it's a nested member expression (#6143) 
close: #6139

I still remember this logic and I call `get_first_object` for it intentionally 🥲

b240b42eb9 fix(rulegen): handle raw string literals correctly (#5991) 
Currently, we are not handling raw string literals correctly and just translating them as normal Rust string literals, which causes compile errors and also misses some cases. This PR updates it so that we detect usage of `String.raw` and translate it as a Rust raw string literal.

d24985ed51 feat(linter): add oxc-security/api-keys (#5906) 
## What This PR does
Adds a new `oxc-security/api-key` rule that scans for hard-coded API keys.

It is broken up into "secret rules", where each one is responsible for finding a different kind of key. It is architecturally identical to how lint rules themselves. This PR also includes the first of these rules, for AWS access key IDs.

Logic and rules are based on [keyhunter](https://github.com/Donisaac/keyhunter). I've licensed that repo under GNU GPLv3, but it's my code and I can do what I want with it 😈 (read: I'm fine with it being MIT for oxc).

This PR is a complete feature in its own right, but does not represent the end of this work. See https://github.com/oxc-project/backlog/issues/116 to track overall progress.
