winston-daily-rotate-file | A transport for winston which logs to a rotating file

Looks like 0% means you missed testing all ifs that are definitely goes to the category Branch.
Try to add tests for one of ifs and see if % Branch will become something like 50%

OK, I figured out the issue. I thought the error was telling me that path was undefined. When it fact it was saying the variables passed into path.join() were undefined. And that was because I forgot to add my .env file to the root so it could grab those variables.

Since it was an enterprise project so they don't keep .env file in the source code, I asked them and put it root.

it's located inside the container, so after running the container,

you have to go to inside the container to see logs if the location is in project directory

You can pass a format value to the timestamp formatter, this can be a string or a function.

The details are here: https://github.com/winstonjs/logform#timestamp

So we can use your timezoned function and the times will be in Europe/Istanbul time, though formatted as US (because of the 'en-US' locale, you can obviously change this as you wish).

I used a workaround with regex now where I replaced newlines with a comma and added [ ] around the file. It looks like this:

I have resolved this issue with below steps :

1. make sure you have internet connection: ping 8.8.8.8
2. make sure you have DNS resolver working: ping www.google.com
3. make sure you can access registry.npmjs.org: ping registry.npmjs.org
4. make sure you can connect via https.

Run below command in npm command prompt or Visual Studio Code terminal.

npm config rm proxy

npm config rm https-proxy

Try in your browser: https://registry.npmjs.org/

Make sure you are trying to connected to:

registry.npmjs.org

and not to:

"registry.npmjs.org registry.npmjs.org:443"

Use below command to set registry.

npm config set registry https://registry.npmjs.org/

If you are using a proxy to access the Web, then you also have to configure npm to use it. Use:

npm config set proxy http://username:password@proxyname:8080

npm config set https-proxy http://username:password@proxyname:8080

Points to remember here while setting above two values :

1. proxyname you need to check with your company network team. Enter that proxy URL in above 2 values.
2. If your password contains any special character then replace it with Encoded character. In this command you can’t provide a password with special character. Replace only special character not .(dot).

   Example: password is : Welcome@12# then it will be like Welcome%4012%23.

Then try to run your npm install command and it should work.

My issue was caused by the datePattern option. winston-daily-rotate-file uses this pattern to determine the frequency of file rotation. As I had included seconds in the pattern it was looking for a file with the current timestamp (to the nearest second) and creating it before writing to file.

To get daily files I just needed to change
