API docs for Space Lua's js module, which provides JavaScript interoperability. js.import(url)
Imports a JavaScript module from a URL. Returns the imported module.Example:-- Import lodash library
local lodashLib = js.import("https://esm.sh/[email protected]")
local result = lodashLib.chunk({1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, 3)
-- Import moment.js for date handling
local momentLib = js.import("https://esm.sh/[email protected]")
local dateObj = momentLib("1995-12-25")
print(dateObj.format("DD-MM-YYYY")) -- prints: 25-12-1995
js.new(constructor, ...)
Creates a new instance of a JavaScript class. Takes a constructor function and its arguments.Example:local DateClass = js.import("https://esm.sh/date-fns")
local dateObj = js.new(DateClass, "2024-03-14")
js.stringify(value)
Converts a Lua value to a JSON string representation.Example:local dataArray = {1, 2, 3}
print(js.stringify(dataArray)) -- prints: [1,2,3]
local nestedArray = lodashLib.chunk({1, 2, 3, 4, 5, 6}, 2)
print(js.stringify(nestedArray)) -- prints: [[1,2],[3,4],[5,6]]
js.tolua(value)
Converts a JavaScript value to its Lua equivalent.Example:local jsArray = someJsFunction()
local luaTable = js.tolua(jsArray)
js.tojs(value)
Converts a Lua value to its JavaScript equivalent.Example:local luaTable = {1, 2, 3}
local jsArray = js.tojs(luaTable)
js.log(...)
Logs messages to the JavaScript console.Example:js.log("Debug message")
js.log("User data:", {name = "John", age = 30})
js.eachIterable(iterable)
Creates an iterator for JavaScript async iterables.Example:local asyncIterator = js.eachIterable(someJsAsyncIterable)
for value in asyncIterator do
print(value)
end
