Tmp Version

TBD:Enter tmp version here
newest

Expected Behavior

TBD:What have you expected tmp to do?
correct temp file.

Experienced Behavior

TBD:What did actually happen?

It generates this file:

let fileName = tmp.tmpNameSync();

undefined\temp\tmp-3476obo4mLnOL8Bp

Then i trying to write to this file:

fs.writeFileSync(fileName, new Buffer(result.data));

no such file or directory, open 'C:\Users\xxx\xx\app-1.0.2\undefined\temp\tmp-3476obo4mLnOL8Bp'

According to the source of os-tmpdir this could only happen if neither of the following environment variables are set: TEMP, TMP, SystemRoot, and windir.

Could you verify that for me please by dumping the process.env.

The following should work:

console.log(JSON.stringify(process.env))

[raszi]

Could you please also show me what os.tmpdir() says to you?

const os = require('os');
console.log(os.tmpdir());

[do-web]

This is working now: tmp.tmpNameSync({ dir: app.getPath('temp') })

Could you please provide the requested information, so we could make sure that tmp works in electron on your Windows platform too? Thank you!

@raszi I believe that tmp should fail early whenever it encounters an undefined tmpdir. What do you think?

[raszi]

@silkentrance I believe that is a good idea!
