编写webpack插件自动找到大文件并上传到指定服务器
编写一个Webpack插件来自动找出大文件并上传到指定服务器
1、创建一个Webpack插件。
2、在插件中监听webpack的特定钩子,比如emit。
3、在emit钩子中,你可以获取编译后的assets,并计算出哪些文件超过了你定义的大小阈值。
4、使用Node.js的http模块或第三方库(如request)发送POST请求上传文件。
以下是一个简单的Webpack插件示例代码:
const http = require('http'); // 或者使用 'https' 如果是https服务器
const fs = require('fs');
const path = require('path');
class UploadLargeFilesWebpackPlugin {
constructor(options) {
this.options = options;
}
apply(compiler) {
compiler.hooks.emit.tapAsync('UploadLargeFilesWebpackPlugin', (compilation, callback) => {
const largeFileSize = this.options.largeFileSize || (1024 * 1024); // 默认1MB
const uploadUrl = this.options.uploadUrl;
Object.keys(compilation.assets).forEach((filename) => {
const asset = compilation.assets[filename];
const fileSize = asset.size();
if (fileSize > largeFileSize) {
const filePath = path.resolve(compiler.options.output.path, filename);
const fileData = fs.readFileSync(filePath);
const uploadRequest = http.request(uploadUrl, {
method: 'POST',
headers: {
'Content-Type': 'application/octet-stream',
'Content-Length': fileData.length
}
}, (response) => {
response.on('data', (chunk) => {
console.log(`BODY: ${chunk}`);
});
response.on('end', () => {
console.log('Upload completed');
});
});
uploadRequest.on('error', (e) => {
console.error(`Problem with request: ${e.message}`);
});
uploadRequest.write(fileData);
uploadRequest.end();
}
});
callback();
});
}
}
module.exports = UploadLargeFilesWebpackPlugin;
使用插件时,在webpack配置文件中如下配置:
const UploadLargeFilesWebpackPlugin = require('./path/to/UploadLargeFilesWebpackPlugin');
module.exports = {
// ... 其他webpack配置
plugins: [
new UploadLargeFilesWebpackPlugin({
largeFileSize: 5242880, // 5MB
uploadUrl: 'http://yourserver.com/upload'
})
]
};
确保替换http://yourserver.com/upload为你的实际上传服务器地址,并且服务器能够处理POST请求并接收文件数据。
