The fileAdded method of vue-simple-uploader does not support asynchronous solutions, autoStart settings

Chicken Soup of the Day: Pessimists Might Be Right, But Optimists Often Succeed

Suppose there is a requirement that the uploaded pdf document should not be larger than 10M

Using the vue-simple-uploader plugin, we need to verify in the fileAdded event. After version 1.0.0, if you want to stop uploading, then return false, continue uploading return true

vue-simple-uploader - npm A Vue.js upload component powered by simple-uploader.js. Latest version: 0.7.6, last published: 3 years ago. Start using vue-simple-uploader in your project by running `npm i vue-simple-uploader`. There are 81 other projects in the npm registry using vue-simple-uploader. https://www.npmjs.com/package/vue-simple-uploader/v/1.0.1 However, there is a Pit, now [July 25, 2023] the fileAdded method does not support asynchronous, that is to say, the following code will not prevent file upload

// 这是一个有问题的方法，return false 并不会阻止文件上传
const fileAdded = async (rootFile: any) => {
	const size = rootFile.size
	// 理想的是，等待 checkFun 方法返回，再决定是否继续上传
	const canUpload = await checkFun(size)
	if (!canUpload) {
		return false
	}
	return true
}

The solution is

1.  Set autoStart = "false" [default is true]
2. Call this.$refs.uploaderRef.uploader.upload() method to upload manually

<uploader
    ref="uploaderRef"
	class="uploader"
	:options="options"
	:file-status-text="statusText"
	@fileAdded="fileAdded"
	:autoStart="false"
	@fileSuccess="fileSuccess"
	@uploadStart="uploadStart"
	@fileError="fileError"
	>
			<!-- 其他内容 -->
</uploader>

// 这个方法没有问题
const fileAdded = async (rootFile: any) => {
	const size = rootFile.size
	const canUpload = await checkFun(size)
	if (canUpload) {
		// 校验通过，手动调用上传方法
		this.$refs.uploaderRef.uploader.upload()
	}
}
