如何在我的npm模块中写入另一个nodejs项目根文件夹

Question

I am writing a npm module that needs to write/create a file in the root folder or in a specific folder in the nodejs project that is going to use my npm module (basically the people who will use my npm module).

How can i do this?

Answer 1

我相信你可以使用process.cwd（）来获取当前的工作目录https://nodejs.org/api/process.html#process_process_cwd

Answer 2

In the end I found that just writeing the name of the file will put it in the root of the project what ever it is.

function writeLog (logMessage) {
    //  put the date on the message log
    fs.appendFile('logsFile.log', logMessage + '\r\n', (err) => {
        if (err) {
            throw err;
        }
    });
}

this code will create or apend in the logsFile.log in the root directory of the project. If it is imported via npm it will write also in the project that uses that module and not in the node_modules project folder.

So that resolves my question.
