使用node.js中的fs覆盖文件的最佳方法是什么 [英] What's the best way to overwrite a file using fs in node.js
问题描述
我正在尝试覆盖现有文件。
我首先检查文件是否存在使用:
I'm trying to overwrite an existing file. I'm first checking if the file exists using:
fs.existsSync(path)
如果文件没有退出我正在使用创建和编写:
If file does not exit I'm creating and writing using:
fs.writeFileSync(path,string)
问题是文件已经存在,我想重写其所有内容。
是否有单行解决方案,到目前为止我搜索并找到了使用
fs.truncate& amp; fs.write,但是有没有一个命中解决方案?
The problem is when the file already exists and I want to over write all its contents. Is there a single line solution, so far I searched and found solutions that use fs.truncate & fs.write, but is there a one hit solution?
推荐答案
fs.writeFileSync
和 fs.writeFile
默认情况下覆盖该文件,如果您想要这样做,则无需额外检查。这在文档中提到:
fs.writeFileSync
and fs.writeFile
overwrite the file by default, there is no need for extra checks if this is what you want to do. This is mentioned in the docs:
异步将数据写入文件,替换文件(如果已存在)。
Asynchronously writes data to a file, replacing the file if it already exists.
