At Node Congress, Socket CEO Feross Aboukhadijeh uncovers the darker aspects of open source, where applications that rely heavily on third-party dependencies can be exploited in supply chain attacks.

Readme
A light weight logger with a status bar on the bottom or the top that does not disappear with scrolling.
You can also attach a verbosity level to each scrollable log call.
Status bar on the bottom:
Status bar on the top:
Install with npm:
npm install log-with-statusbar
const log = require("log-with-statusbar")();
// Set the bottom status lines
// Each line is an entry of the array
log.setStatusBarText([
`This is non-scrollable status bar line 1`,
`This is non-scrollable status bar line 2`
]);
// Normal scrollable system logs
let i = 0;
setInterval(() => {
log.info(`This is a normal scrollable log ${i++}`);
}, 1);
Several examples are available in examples folder:
You can add or remove lines to the status bar
// Adds one line to the status bar (See examples/push_pop_demo.js)
log.statusBarTextPush(`Adding one line to the status bar`);
// Removes one line from the status bar (See examples/push_pop_demo.js)
log.statusBarTextPop(`Remove the last line from the status bar`);
You can enable/disable the status bar or both scrollable log and status bar. See examples/enable.js
// Disables the status bar
log.disableStatusBar();
// Enables the status bar
log.enableStatusBar();
// Completely disables logging both scrollable and status bar
log = log.disable();
// Completely enables logging both scrollable and status bar
log = log.enable();
You can use create pre-designed spinners. credit to cli-spinners. See Spinner example and spinners.json file.
// Returns an object created from the spinners.json file
let spinners = log.getSpinners();
If you just want to use the status bar and also setup ololog parameters, you can set the following:
const log = require("log-with-statusbar")({
ololog_configure: {
locate: false,
tag: true
}
});
ololog_configure
: sets the ololog configurations. All features of ololog are available.
The following settings are for the status bar behavior:
const log = require("log-with-statusbar")({
initialStatusTextArray: [`Please wait...`],
enableStatusBar: true,
position: "top" // Default value is "bottom"
});
Pushing keys while showing the status bar might disturb the output. You can disable input keys except for CTRL+C using disableInput
, which is set to false by default:
const log = require("log-with-statusbar")({
initialStatusTextArray: [`Please wait...`],
disableInput: true
});
Besides globally enabling and disabling the log, you can attach a verbosity level to each scrollable log call. Each log call will print out its output only if the attached verbosity level is less than or equal to the global minimum verbosity level:
log.verbosity(n).info("Test");
attaches verbosity level n
to this call.log.info("Test");
attaches verbosity the default verbosity level to this call.log = log.maxVerbosity(1000);
will change the global maximum verbosity levelBelow is an example:
// We only print if verbosity is less than or equal maxVerbosity
var log = require("log-with-statusbar")({
maxVerbosity: 1, //maximum verbosity level
verbosity: 1, //Default verbosity level
enableStatusBar: false
});
// Non-verbose mode: The lines with verbosity 2 and 3 won't print
log("This prints because (1 <= 1)= true");
log.verbosity(2).info("Less important line 1");
log.verbosity(3).info("Even less important line 2");
console.log("\nLet's be more verbose!\n");
// Let's be more verbose: The lines with verbosity 2 and 3 will now print
log = log.maxVerbosity(3);
log("This prints because (1 <= 3)= true");
log.verbosity(2).info("Less important line 1");
log.verbosity(3).info("Even less important line 2");
And here is a more complicated example:
var log = require("log-with-statusbar")({
maxVerbosity: 1, //maximum verbosity level
verbosity: 1, //Default verbosity level
enableStatusBar: false
});
// We only print if verbosity is less than or equal maxVerbosity
log("This prints using default verbosity level: (1 <= 1)= true");
// Attaching verbosity level 1
log.verbosity(1).info("This will print, (1 <= 1) = true");
// Attaching verbosity level 17
log.verbosity(17).info("This won't print, (17 <= 1) = false");
//Let's be more verbose now!
log.info("Changing maxVerbosity to 1000");
log = log.maxVerbosity(1000);
log.verbosity(17).info("This will print, (17 <= 1000) = ture");
log.verbosity(12).info("This will print, (12 <= 1000) = true");
log.verbosity(1).info("This will print, (1 <= 1000) = true");
log.verbosity(1500).info("This won't print, (1500 <= 1000) = false");
//Default verbosity level is still 1
log.info("This will print, (1 <= 1000) = true");
// Changing default verbosity level
log = log.verbosity(1600);
log.info("This won't print, (1600 <= 1500) = false");
