### [1.6.0](https://github.com/grimmer0125/d4c-queue/compare/v1.5.10...v1.6.0) (2021-05-07)

⭐ Decorator concurrency mode ⭐ is added.

```ts
@QConcurrency([
  { limit: 100, isStatic: true },

])
class TestController {
  @concurrent
  static async fetchData(url: string) {}
```

#### ⚠ BREAKING CHANGES

```ts
// orig: only setup one queue, omitting tag will apply default queue and new tag queue
d4c = new D4C({ concurrency: { limit: 100 } })
d4c.setConcurrency({ limit: 10 })

// new. to setup multiple queue, omitting tag will only for deafult queue and not apply on new tag queue
d4c = new D4C([{ concurrency: { limit: 100 } }])
d4c.setConcurrency([{ limit: 10 }])
```

### [1.5.10](https://github.com/grimmer0125/d4c-queue/compare/v1.5.9...v1.5.10) (2021-05-07)

#### ⚠ BREAKING CHANGES

```ts
/** orig */
d4c.setQueue({ concurrency: 10 })

/** new, rename parameter */
d4c.setConcurrency({ limit: 10 })
```

- Allow D4C constructor can setup tag queue concurrency limit. `const d4c = new D4C({ limit: 100, tag: '2' });`
- Improve README.

### [1.5.9](https://github.com/grimmer0125/d4c-queue/compare/v1.5.4...v1.5.9) (2021-05-07)

#### ⚠ BREAKING CHANGES

```ts
const d4c = new D4C(100)
```

To

```ts
const d4c = new D4C({ concurrency: 100 })
```

### [1.5.0](https://github.com/grimmer0125/d4c-queue/compare/v1.4.5...v1.5.0) (2021-05-07)

⭐ New API ⭐ and minor bug fixes

Add concurrency mode support for D4C instance usage. Previous it only supports synchronization mode (concurrency = 1).

```ts
const d4c = new D4C(100)
d4c.setQueue({ concurrency: 10 }) // change default concurrency from 1 to 10
d4c.setQueue({ concurrency: 10, tag: 'queue2' }) // concurrency for queue2
```

### [1.3.0](https://github.com/grimmer0125/d4c-queue/compare/v1.2.6...v1.3.0) (2021-05-02)

#### ⚠ BREAKING CHANGES

- Improve queue system. Each instance/class is isolated with the others.
- API breaking change. No more global usage. no more ~~dApply, dWrap~~, and add needed `@injectQ`.
- back to es6 for main build.

original:

```ts
import { D4C, dApply, dWrap, synchronized } from 'd4c-queue'

/** global usage*/
const asyncFunResult = await dWrap(asyncFun, { tag: 'queue1' })(
  'asyncFun_arg1',
  'asyncFun_arg2'
)

/** instance usage */
const d4c = new D4C()
d4c.apply(async)

/** decorator usage */
class ServiceAdapter {
  @synchronized
  async connect() {}
}
```

becomes

```ts
import { D4C, injectQ, synchronized } from 'd4c-queue'

/** instance usage */
d4c.apply(syncFun, { args: ['syncFun_arg1'] })

/** decorator usage */
@injectQ
class ServiceAdapter {
  @synchronized
  async connect() {}
}
```

Refactor API and instance method renaming

Change static method to public function:

```ts
D4C.apply -> dApply
D4C.wrap -> dWrap
D4C.synchronized -> synchronized
D4C.register -> defaultTag
```

Change instance method naming:

```ts
iapply -> apply
iwrap -> wrap
```

### [1.1.5](https://github.com/grimmer0125/d4c-queue/compare/v1.1.4...v1.1.5) (2021-04-28)
