在基于 Unix 系统的MacOS以及Linux中都可以使用管道运算符(|),它可以将运算符左侧进程的输出转换成右侧的输入。 在Node 中,我们使用传统的 readFile 去读取文件的话,会将文件从头到尾都读到内存中,当所有内容都被读取完毕之后才会对加载到内存中的文件内容进行统一处理。 这样做会有两个缺点: 内存方面:占用大量内...
2、fs.appendFileSync使用说明。 fs.appendFileSync(filename, data, [options]) 该方法功能与 fs.appendFile() 类似,唯一区别就是该方法是用同步操作,而fs.appendFile使用的是异步。 接收参数: 1. filename {String} 2. data {String | Buffer} 3. options {Object} encoding {String | Null} default = ...

We can also pass an options object or string that specifies the encoding to use, as well as mode and flag. If you need to specify the character encoding then here is the way you'll need to call the method: fs.writeFile('2pac.txt', 'Some other lyric', 'ascii', callback); Note...
fs.writeFile('./out', data, () => {}) }) 通过活动监视器,我们发现该进程内存占用为 300 MB 左右: 如果,我们换成流,情况就不一样了: const fs = require('fs') const readStream = fs.createReadStream('./big.file') const writeStream = fs.createWriteStream('./out') readStream.pipe(wr...
