# image-tools
图像转换工具，可用于如下环境：uni-app、微信小程序、5+APP、浏览器（需允许跨域）
## 使用方式
### NPM
```
npm i image-tools --save
```
```js
import { pathToBase64, base64ToPath } from 'image-tools'
```
### 直接下载
```js
// 以下路径需根据项目实际情况填写
import { pathToBase64, base64ToPath } from '../../js/image-tools/index.js'
```
## API
### pathToBase64
从图像路径转换为base64，uni-app、微信小程序和5+APP使用的路径不支持网络路径，如果是网络路径需要先使用下载API下载下来。
```js
pathToBase64(path)
.then(base64 => {
console.log(base64)
})
.catch(error => {
console.error(error)
})
```
### base64ToPath
将图像base64保存为文件，返回文件路径。
```js
base64ToPath(base64)
.then(path => {
console.log(path)
})
.catch(error => {
console.error(error)
})
```
## 提示
可以利用promise来串行和并行的执行多个任务
```js
// 并行
Promise.all(paths.map(path => pathToBase64(path)))
.then(res => {
console.log(res)
// [base64, base64...]
})
.catch(error => {
console.error(error)
})
// 串行
paths.reduce((promise, path) => promise.then(res => pathToBase64(path).then(base64 => (res.push(base64), res))), Promise.resolve([]))
.then(res => {
console.log(res)
// [base64, base64...]
})
.catch(error => {
console.error(error)
})
```
