Chrome-like in-browser console
Available methods:
loginfo— same aslogdirerrorwarn— same aserrorlogHTML— same aslog, but strings won't be escaped

-
htmlacademy.github.io/console.js/latest/js/presets/htmlacademy.js— confifures behaviour, but not enabling autoexpand. All objects will show only up to5properties it preview (header). Configures autoexpand to be triggered only if there're from5to15properties. Excludes__proto__property from autoexpand. Functions bodies will be collapsed. -
htmlacademy.github.io/console.js/latest/js/presets/autoexpand-all.js— Enabling autoexpand of all objects by1level.
You can use both to enable autoexpanding with defined behaviour.

<script src="//htmlacademy.github.io/console.js/latest/js/index-silent.js"></script>Lower connected preset script has higher priority than others. Will be merged with lodash.mergeWith using concatinating arrays
const jsConsole = new Console(DOMElement, config);You can specify 3 types of views here: object, function and array.
And common, that has lower priority than concrete. Will be merged into concrete one
with lodash.mergeWith using concatinating arrays
expandDepth— depth on which fields of this root object will be expanded. Default:0.maxFieldsInHead— max length of properties in preview (head). If has more,...at the end will be showed. Default:5.minFieldsToAutoexpand— min length of fields in view type to auto expand. Default:0.maxFieldsToAutoexpand— max length respectively. Default:Positive infinity.excludeViewTypesFromAutoexpand— array of view types that don't need to be expanded inside that root view type.showGetters— specifies ifgetandsetmethods will be showed in expanded object body. Default:true.showMethodBodyOnly— if function is a method of any type of object — shows only body of this function (in opened object).excludePropertiesFromAutoexpand— properties in view type which wouldn't be auto expanded.removeProperties— array of properties to remove from view.
Specific properties for array:
countEntriesWithoutKeys— useful only ifmaxFieldsInHeadgiven. Specifies if indexed properties should be counted in preview (head). Default:false.
Specific properties for function:
nowrapOnLog— specifies if functions bodies will be collapsed. Default:false.
Example:
{
object: {
expandDepth: 2,
minFieldsToAutoexpand: 1, // will expand if object has 1 or more enumerable fields
excludeViewTypesFromAutoexpand: [`function`, `array`] // will not expanded inside object,
showMethodBodyOnly: true // show method's body only (if object was opened)
},
function: {
expandDepth: 1 // will expand only itself (in dir mode only),
nowrapOnLog: true // On log will collapse function body
},
array: {
expandDepth: 2, // expand 2 levels
minFieldsToAutoexpand: 4, // if there is 4 enum fields in array
excludeViewTypesFromAutoexpand: [`object`] // objects inside array won't be expanded
countEntriesWithoutKeys: true
},
common: {
expandDepth: 1,
maxFieldsInHead: 6, // object and array will have up to 6 properties in their previews (headers)
maxFieldsToAutoexpand: 10 // if there's more than 10 properties in obj of any type, it won't be expanded
}
}This config:
{
object: {
maxFieldsToAutoexpand: 10,
excludeViewTypesFromAutoexpand: [`object`]
},
common: {
expandDepth: 1
maxFieldsToAutoexpand: 15,
excludeViewTypesFromAutoexpand: [`array`]
}
};will be transformed into this on application start:
{
object: {
maxFieldsToAutoexpand: 10,
expandDepth: 1,
excludeViewTypesFromAutoexpand: [`object`, `array`]
}
}Using lodash.mergeWith to merge objects and concat arrays inside them
You have 2 preset files:
<script src="//htmlacademy.github.io/console.js/latest/js/presets/preset-1.js"></script>
<script src="//htmlacademy.github.io/console.js/latest/js/presets/preset-2.js"></script>
<script src="//htmlacademy.github.io/console.js/latest/js/index-silent.js"></script>preset-1.js contains:
{
object: {
maxFieldsToAutoexpand: 5,
excludeViewTypesFromAutoexpand: [`object`]
},
common: {
excludeViewTypesFromAutoexpand: [`function`]
}
}preset-2.js contains:
{
object: {
maxFieldsToAutoexpand: 10
},
common: {
expandDepth: 1
excludeViewTypesFromAutoexpand: [`array`]
}
}result will be:
{
object: {
maxFieldsToAutoexpand: 10,
excludeViewTypesFromAutoexpand: [`object`]
},
common: {
expandDepth: 1
excludeViewTypesFromAutoexpand: [`array`, `function`]
