Npm debug log

GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. New version of : This should prevent mishaps likewhile avoiding overly configurable options that make it hard to predict where the file will show up. Fix Close This has been rebased and tests fixed. Not sure how I feel about this patch on its own, but it does inch us a little of the way towards npm report.

I had a thought about this: if two npm instances run at the same time, wouldn't they clobber npm-debug. I am deliberately not describing it as a cache, because I don't want to create another client of the cache code if the cache code is going to be rewritten soon. More like a plumbing trap; like the J-bend in a sink. The log list will have LRU semantics. These log files get pretty hefty, so probably set the default to 10 which could easily use up to MiB on disk.

As for the rest, get this working and we can iterate from there. I have a strawman version of the logic I outlined already implemented. Let me push it to my fork of npm and we can prune it from there. I got it about what will happen for npm-debug. It's sensitive about disk size, so I think it's good if set a limit of a size saved log in npm. Apart from that, maybe one change has needed at here :.

Also, isaacs apparently decided it needed to be closed out when he had a little boo boo with his git branches a few weeks ago, so we'd need to redo it anyway if we wanted to land it. Either way, this is a supportability feature that should be tackled as such.

So wait othiym23 I am not sure what the outcome is here. The npm-debug file now gets put deep in this. The location is not configurable - it has just been moved. Is this correct? Is this still the case? Sucks for me as this is buried in a hidden folder in windows called AppData. Yeah I can get to it but I don't want to take a spaceship to the moon just get a better view of the sun either. So log output is not configurable?

What a shame. This is incredibly inconvenient for CI environments, where several CI engines are able to report you error and success logs located on certain directories.You may unsubscribe at any time using the unsubscribe link in the digest email.

If you search on how to debug JavaScript you'll find hundreds of blog posts and StackOverflow articles pointing you to "simply" console. But what if we actually want to log something intentionally to provide more information? In this blog post we'll look at various situations where you want to log info, what the difference between console. While you are able to use console. When you write the following code in Node.

And execute it in the terminal using node index. However, while those two might look the same, they are actually treated by the system differently.

A Guide to Node.js Logging

If you check the console section of the Node. Every process has three default streams that it can work with. Those are stdinstdout and stderr. The stdin stream is handling the input that comes to your process.

For example button presses or a redirected output we'll get to that in a second. Lastly stderr is meant for error messages. If you want to understand why stderr exists and when to use it, check out this article. Now that we've learned a bit about the underlying tech aspect of logging, let's talk a bit about different use cases where you might want to log something.

Typically these use cases fall into one of the following categories:. There's a variety of reasons why you might want to log things on your server.

Logging incoming requests for example allows you to extract things like statistics out of it, such as how many s users are hitting, what those might be or what User-Agent is being used. And you also want to know when stuff went wrong and why.

If you want to try out the things following in this part of the post, make sure to create a new project directory.

Create an index. Let's set up a server with a middleware that just console. Place the following into the index. We are using console. You can read about them in the Node. When you run node index.A tiny JavaScript debugging utility modelled after Node. Works in Node. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. Example app. Example worker. Every debug instance has a color generated for it based on its namespace name.

This helps when visually parsing the debug output to identify which debug instance a debug line belongs to. In Node. You also should install the supports-color module alongside debug, otherwise debug will only use a small handful of basic colors. These are WebKit web inspectors, Firefox since version 31 and the Firebug plugin for Firefox any version. When actively developing an application it can be useful to see when the time spent between one debug call and the next.

If you're using this in one or more of your libraries, you should use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you should prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". You can then use it for normal output as well as debug output.

You can also exclude specific debuggers by prefixing them with a "-" character. When running through Node. See the Node. Debug uses printf-style formatting. Below are the officially supported formatters:. You can add custom formatters by extending the debug. You can build a browser-ready script using browserifyor just use the browserify-as-a-service buildif you don't want to build it yourself. Debug's enable state is currently persisted by localStorage. Consider the situation shown below where you have worker:a and worker:band wish to debug both.

You can enable this using localStorage. By default debug will log to stderr, however this can be configured per-namespace by overriding the log method:. Example stdout. Usage : enable namespaces namespaces can include modes separated by a colon and wildcards.

Will disable all namespaces. The functions returns the namespaces currently enabled and skipped. This can be useful if you want to disable debugging temporarily without knowing what was enabled to begin with.

Note: There is no guarantee that the string will be identical to the initial enable string, but semantically they will be identical. After you've created a debug instance, you can determine whether or not it is enabled by checking the enabled property:. You can also manually toggle this property to force the debug instance to be enabled or disabled. Support us with a monthly donation and help us continue our activities.

You can also bring up the snippets with the Add Configuration By default, Node.Given how widespread it is and the convenience of namespaces it is a great logger for library modules. Each instance of debug-logger will lazily instantiate several instances of debug such as namespace:infonamespace:warnnamespace:erroretc.

I noticed that the error had to do with the file I am linking to the path, specifically when npm tried to do a chmod.

After digging through the npm docs I found an option that would stop npm from making the bin links --no-bin-linkswhen I tried the install with it, it worked fine. So what's the deal? Is this some weird fringe case bug that has no solution yet? Edit: For reference, here is the module I uploaded.
