Creating custom machine upgrade with KubeJS

//Use the 'cm_upgrades' event to register custom machine upgrades.
onEvent('cm_upgrades', event => {

//Create an upgrade from the item you want, ex: vanilla diamond.
//You must also specify the max amount of this upgrade the machine can accept, ex: 64.
//Syntax: event.create(Item.of("item_id"), maxAmount)
event.create(Item.of('minecraft:diamond'), 64)

//Add a machine that can accept this upgrade, you can use this method several times to add differents machines.
//You MUST specify at least one machine or the upgrade will not be created and an error will be thrown.
//Syntax: .machine("machine_id")
.machine("custommachinery:power_crusher")

//You can add a custom tooltip to the machine upgrade item.
.tooltip('Ultra booster MK3')

//Add various requirement modifiers using the methods below.

//Add an addition modifier for all input requirements of type: "requirement_id".
//"target" is for specifying  a specific property of the requirement, ex: "chance" to modify the "chance" property of requirements that have this property.
//chance is a value between 0.0 and 1.0 that define the chance of the modifier to be applied.
.addInput("requirement_id", value)
.addInput("requirement_id", value, "target")
.addInput("requirement_id", value, chance)
.addInput("requirement_id", value, "target", chance)

//Add a multiplication modifier for all input requirements of type: "requirement_id".
//"target" is for specifying  a specific property of the requirement, ex: "chance" to modify the "chance" property of requirements that have this property.
//chance is a value between 0.0 and 1.0 that define the chance of the modifier to be applied.
.mulInput("requirement_id", value)
.mulInput("requirement_id", value, "target")
.mulInput("requirement_id", value, chance)
.mulInput("requirement_id", value, "target", chance)

//Add an addition modifier for all output requirements of type: "requirement_id".
//"target" is for specifying  a specific property of the requirement, ex: "chance" to modify the "chance" property of requirements that have this property.
//chance is a value between 0.0 and 1.0 that define the chance of the modifier to be applied.
.addOutput("requirement_id", value)
.addOutput("requirement_id", value, "target")
.addOutput("requirement_id", value, chance)
.addOutput("requirement_id", value, "target", chance)

//Add a multiplication modifier for all output requirements of type: "requirement_id".
//"target" is for specifying  a specific property of the requirement, ex: "chance" to modify the "chance" property of requirements that have this property.
//chance is a value between 0.0 and 1.0 that define the chance of the modifier to be applied.
.mulOutput("requirement_id", value)
.mulOutput("requirement_id", value, "target")
.mulOutput("requirement_id", value, chance)
.mulOutput("requirement_id", value, "target", chance)
})

Examples

A gold ingot put inside the Power Crusher will double it's energy comsumption but also increase the speed by 50%.

onEvent('cm_upgrades', event => {
    event.create(Item.of('minecraft:gold_ingot'), 64)
    .machine("custommachinery:power_crusher")
    .mulInput('custommachinery:energy', 2)
    .mulInput('custommachinery:speed', 1.5)
})
