This package allows you to give style to your JSON on your console!
$ npm install jsome
if you need to use jsome as a command line, you may need to instal it globally
$ [sudo] npm install -g jsome
Using jsome as a command line, you need to run the following command that takes the path to your json file as argument
$ jsome /path/to/your/json/file.json
$ jsome [options] /path/to/your/json/file.json
You can also send a json string through a pipe (|
)
$ cat /path/to/your/json/file.json | jsome
The options available are :
-c
: to enable or disable colors (defualt value: true)-l
: to enable or disable levels (default value: false)-s
: to specify the number of tabulation spaces (default value: 2)-r
: to specify valid JSON as output (default value: true)
examples :
$ jsome -c false /path/to/your/file.json
$ jsome -c false -l true /path/to/your/file.json
$ jsome -s 4 /path/to/your/file.json
On your nodejs application, when you need to console.log a json object, all you need to do is to use the jsome function
var jsome = require('jsome');
jsome([{"id":1,"email":"[email protected]","active":true},{"id":2,"email":"[email protected]","active":false},{"id":3,"email":"[email protected]","active":true}]);
Then your json object will be displayed on the console in a pretty format with Awsome colors ! Here is the result :
The jsome
function returns the object passed as argument so that when debugging, you can print the value of an object without having to change a lot on your code
// instead of
var foo = {
bar : obj
}
jsome (obj);
// you can do this :
var foo = {
bar : jsome(obj)
}
You can add some points to show levels of elements... very helpful when you are dealing with complex json objects
jsome.level.show = true;
The object jsome.level
has as default value the following json :
jsome.level = {
'show' : false
, 'char' : '.'
, 'color' : 'red'
, 'spaces' : 2
, 'start' : 0
}
You can change the level char, its color ( see chalk package ) and the number of spaces for each level.
You can also display your json starting from a specific level to avoid displaying your json starting from the extreme left. You can do that by changing the value jsome.level.start
.
You can configure the colors of the displayed json by changing the values of the jsome.colors
object which has as default these values.
jsome.colors = {
'num' : 'cyan' // stands for numbers
, 'str' : 'magenta' // stands for strings
, 'bool' : 'red' // stands for booleans
, 'regex' : 'blue' // stands for regular expressions
, 'undef' : 'grey' // stands for undefined
, 'null' : 'grey' // stands for null
, 'attr' : 'green' // objects attributes -> { attr : value }
, 'quot' : 'yellow' // strings quotes -> "..."
, 'punc' : 'yellow' // commas seperating arrays and objects values -> [ , , , ]
, 'brack' : 'yellow' // for both {} and []
}
You can not only use the color value as string but also you can use an array to specify the background color or you can make things look bold ( see chalk package for more details )
jsome.colors.bool = ['green' , 'bgRed']
jsome.colors.attr = ['green' , 'bold']
jsome.colors.quot = ['yellow', 'bold']
jsome.colors.punc = ['yellow', 'bold']
jsome.colors.brack = ['yellow', 'bold']
When you have a json as a string, instead of passing by JSON.parse
function, you can just call the parse function of jsome
jsome(JSON.parse('[1,2,3]'));
becomes:
jsome.parse('[1,2,3]');
If you need to disable the colors:
jsome.params.colored = false;
If you need JSON which pases linting:
jsome.params.lintable = true;
When you have a very long json to display, don't make your code blocking... you can enable the asynchronous mode.
jsome.params.async = true;
jsome(longJson, function () {
/* Your code here */
});
The default value of params
is:
jsome.params = {
'colored' : true
, 'async' : false
, 'lintable': false
}
In order to get the colored string without printing it on the console :
var coloredString = jsome.getColoredString(obj)
