Question

I have the following issue, in the function sendDownload(downlodable,objPathArray, responseObject) I am receiving the parameter objPathArray like this:

[{"pathToFile":"./REPORTS/portfolio/onDemand/Portfolio_report_HP_17.08.2021.xlsx","file":"Portfolio_report_HP_17.08.2021.xlsx"}]

The function:

function sendDownload(downlodable ,objPathArray, responseObject) {    
    if (downlodable) {  
        responseObject.download((objPathArray[0].pathToFile), (objPathArray[0].file))      
        console.log('HERE ' + JSON.stringify(objPathArray))        
    }
}

but when I call the function in my app I receive this error Error: ENOENT: no such file or directory, stat 'C:\Work\reporting-server\REPORTS\portfolio\onDemand\Portfolio_report_HP_17.08.2021.xlsx' and that's because Node is changing my relative path for the file in an absolute one. What is the best option for me in order to solve this issue?

Thank you~

Node.js must resolve the path to find the file.

If you give it a relative path then it has to start somewhere and that somewhere is the current working directory.

If you want it to read the file from somewhere else then resolve it to an absolute path yourself.

Generally speaking the tools to do this will be path.resolve and something to tell it where to start from such as a configuration file , environment variable , orthe directory the module is in .
