File System interaction for an nRF Connect for Desktop application

[Alasdair Scott]

It would be useful to read and write other local files apart from the default 'logger', say, to maintain separate custom logs for multiple discovered devices.  However modules like 'fs' and 'path' etc. are not directly available from pc-nrfconnect-shared.

Is there a way to achieve this?

Hi,

The log transports are hardcoded in the logger module. Depending on your needs, you may have to make a parallel log implementation in order to get the logging functionality that you want. The logger module builds on winston.

I'll register suggestions to the team for exposing more flexible logging options.

Thank you for the prompt reply Terje,

It prompted me to try another approach!

Initially I tried:

import { logger, getUserDataDir, fs, path } from 'nrfconnect/core';

or

import { fs, path } from 'pc-nr-connect-shared';

but now realise that it should have been:

import fs from 'fs';
import path from 'path';
import { logger, getUserDataDir } from 'nrfconnect/core';
...
const filename = path.join(USER_DATA_DIR, 'test.log');
logger.info(filename);
fs.writeFileSync(filename, 'Lorem Ipsum');

Which now works.

Apologies - and I hope this may help someone else...

Hi,

Thank you for the update. Yes, that should work. Provided that version dependencies and package manager are both reasonable, this should lead to shared use.
