## Example

[preview](https://hezhongfeng.github.io/vue-page-stack-example/)

[demo code](https://github.com/hezhongfeng/vue-page-stack-example)

## Features

- 🐉expanded on vue-router, the original navigation logic remains unchanged
- ⚽When a page is re-rendered as a `push` or `forward`, the newly rendered page will be added to the Stack.
- 🏆When `back` or `go(negative number)`, the previous pages are not re-rendered, but instead are read from the Stack, and these pages retain the previous content state, such as the form content, the position of the scroll bar
- 🏈`back` or `go (negative)` will remove unused pages from the Stack
- 🎓`replace` will update the current page in the stack
- 🎉activated hook function triggers when rolling back to the previous page
- 🚀Browser back and forward events are supporded
- 🍕Responding to changes in routes with Parameters is supporded, such as navigating from `/user/foo` to `/user/bar`, component instances are reused
- 🐰provides routing direction changes, and you can add different animations when forward or backward

```

```

## API

### install

```
Vue.use(VuePageStack, options);
// example
Vue.use(VuePageStack, { router });
```

Options description：

Attribute | Description | Type | Accepted Values | Default
---|---|---|---|---
router | vue-router instance | Object | vue-router instance | -
name | VuePageStack name | String | 'VuePageStack' | 'VuePageStack'
keyName | stack-key name | String | 'stack-key' | 'stack-key'

you can customize VuePageStack's name and keyName
```
Vue.use(VuePageStack, { router, name: 'VuePageStack', keyName: 'stack-key' });
```

### forward or backward
If you want to make some animate entering or leaving, `vue-page-stack` offers `stack-key-dir` to judge forward or backward.

```
// App.vue
$route(to, from) {
  if (to.params['stack-key-dir'] === 'forward') {
    this.transitionName = 'forward';
  } else {
    this.transitionName = 'back';
  }
}
```
[example](https://github.com/hezhongfeng/vue-page-stack-example/blob/master/src/App.vue)

### get current UI stack
```
let UIStack = this.$pageStack.getStack();

```
[example code](https://github.com/hezhongfeng/vue-page-stack-example/blob/814f5ad8b8804e6fd81002f7254d266df3311770/src/views/main/MainList.vue#L30)
## Notes

### keyName

Why is the parameter `keyName` added to the route? To support the browser's backward and forward events，this is important in webApp or wechat.

### Changelog
Details changes for each release are documented in the [release notes](https://github.com/hezhongfeng/vue-page-stack/releases).

### Principle

Getting the current page instance refers to the `keep-alive` section of `Vue`.
