### [`v0.17.15`](https://togithub.com/evanw/esbuild/blob/HEAD/CHANGELOG.md#01715)
[Compare Source](https://togithub.com/evanw/esbuild/compare/v0.17.14...v0.17.15)
- Allow keywords as type parameter names in mapped types ([#3033](https://togithub.com/evanw/esbuild/issues/3033))
TypeScript allows type keywords to be used as parameter names in mapped types. Previously esbuild incorrectly treated this as an error. Code that does this is now supported:
```ts
type Foo = 'a' | 'b' | 'c'
type A = { [keyof in Foo]: number }
type B = { [infer in Foo]: number }
type C = { [readonly in Foo]: number }
```
- Add annotations for re-exported modules in node ([#2486](https://togithub.com/evanw/esbuild/issues/2486), [#3029](https://togithub.com/evanw/esbuild/issues/3029))
Node lets you import named imports from a CommonJS module using ESM import syntax. However, the allowed names aren't derived from the properties of the CommonJS module. Instead they are derived from an arbitrary syntax-only analysis of the CommonJS module's JavaScript AST.
To accommodate node doing this, esbuild's ESM-to-CommonJS conversion adds a special non-executable "annotation" for node that describes the exports that node should expose in this scenario. It takes the form `0 && (module.exports = { ... })` and comes at the end of the file (`0 && expr` means `expr` is never evaluated).
Previously esbuild didn't do this for modules re-exported using the `export * from` syntax. Annotations for these re-exports will now be added starting with this release:
```js
// Original input
export { foo } from './foo'
export * from './bar'
// Old output (with --format=cjs --platform=node)
...
0 && (module.exports = {
foo
});
// New output (with --format=cjs --platform=node)
...
0 && (module.exports = {
foo,
...require("./bar")
});
```
Note that you need to specify both `--format=cjs` and `--platform=node` to get these node-specific annotations.
- Avoid printing an unnecessary space in between a number and a `.` ([#3026](https://togithub.com/evanw/esbuild/pull/3026))
JavaScript typically requires a space in between a number token and a `.` token to avoid the `.` being interpreted as a decimal point instead of a member expression. However, this space is not required if the number token itself contains a decimal point, an exponent, or uses a base other than 10. This release of esbuild now avoids printing the unnecessary space in these cases:
```js
// Original input
foo(1000 .x, 0 .x, 0.1 .x, 0.0001 .x, 0xFFFF_0000_FFFF_0000 .x)
// Old output (with --minify)
foo(1e3 .x,0 .x,.1 .x,1e-4 .x,0xffff0000ffff0000 .x);
// New output (with --minify)
foo(1e3.x,0 .x,.1.x,1e-4.x,0xffff0000ffff0000.x);
```
- Fix server-sent events with live reload when writing to the file system root ([#3027](https://togithub.com/evanw/esbuild/issues/3027))
This release fixes a bug where esbuild previously failed to emit server-sent events for live reload when `outdir` was the file system root, such as `/`. This happened because `/` is the only path on Unix that cannot have a trailing slash trimmed from it, which was fixed by improved path handling.
