Beginning of #6347. Instead of using serde-derive, we generate
`Serialize` impls manually.

See https://babel.dev/docs/options#misc-options for background on `unambiguous`
Once `SourceType::Unambiguous` is parsed, it will correctly set the returned `Program::source_type` to either `module` or `script`.
This also removes the confusing `SourceType::always_strict` field.
I hacked it with `SourceType::always_strict`, but what we actually want is add `'use strict'`.
This is technically a breaking change but I don't expect anyone using this outside of oxc.
The snapshot has a large diff due to every single line shifting by 1 row :-/
Use `std:#️⃣:Hasher` instead of `core:#️⃣:Hasher`.
I don't actually know if importing `core` as well as `std` has any compile time perf impact, but as we're using `std` anyway, we may as well use it for everything.
Import into the `auto_impl_content_hash` module to make the macro a little easier to read.
Adds `no-async-endpoint-handlers` rules, which bans async functions used as endpoint handlers in Express applications. These do not get caught by Express' error handler, causing the server to crash with an unhandled process rejection error.
```js
app.use(async (req, res) => {
const foo = await api.getFoo(req.query) // server panics if this function rejects
return res.json(foo)
})
```
I could not find this rule implemented in any ESLint plugin, but this is a problem I see quite often and I'm tired of dealing with it. I've added it to `oxc` for now, but we should consider adding an `express` or `api` plugin in the future.
- fix: `SourceType::from_path` considers `.cjs` and `.cts` as modules, not scripts
- docs: improve rusdoc for `SourceType::from_path`
- test: add unit tests for `SourceType::from_path`
We mostly use `allocator` as var name for an `Allocator`, but in some places used the shorter name `alloc`. Use `allocator` everywhere for consistency.
I got tired of seeing useless spreads on ternaries and `arr.reduce()` within my company's internal codebase so I overhauled this rule.
## Changes
- add fixer for object spreads
```js
const before = { a, ...{ b, c }, d }
const after = { a, b, c, d } // fixer does not dedupe spaces before `b`
```
- recursively check for useless clones on complex expressions. This rule now catches and auto-fixes the following cases:
```js
// ternaries when both branches create a new array or object
const obj = { ...(foo ? { a: 1 } : { b: 2 }) }
// recursive, so this can support complex cases
const arr = [ ...(foo ? a.map(fn) : bar ? Array.from(iter) : await Promise.all(bar)) ]
// reduce functions where the initial accumulator creates a new object or array
const obj = { ...(arr.reduce(fn, {}) }
```
Similar to #4375 and #4698. #4696 added `#[ast]` attribute to types in `oxc_span`, so these types can use `#[serde]` attrs without the `#[cfg_attr(feature = "serialize", ...)]` guard.
Closes#4606.
Introduce `GetSpanMut` trait and implement it on all AST node types.
This has to be a separate trait, rather than adding `span_mut` method to `GetSpan` because `AstKind` implements `GetSpan`, and it only has an immutable `&` ref to AST node it contains.
