Python portals to JS

class jy.bridge.JsBridge

The default class to make instances that will contain methods that mirror JS function calls

jy.bridge.add_js_funcs(js_code: str, *, obj: Any = None, name: str | None = None, encoding: str | None = None, forbidden_method_names=(), apply_defaults=True, value_trans=<function dflt_py_to_js_value_trans>)

Add js call functions as attributes to an object.

If object is not given, add_js_funcs will use a new JsBridge instance.

>>> js_code = """
... function foo(a, b="hello", c= 3) {
...     return a + b.length * c
... }
... const bar = (y, z = 1) => y * z
... func.assigned.to.nested.prop = function (x) {
...     return x + 3
... }
... """
>>> js = add_js_funcs(js_code)
>>> from inspect import signature
>>> list(vars(js))
['foo', 'bar', 'prop']
>>> signature(js.foo)
<Sig (a, b='hello', c=3)>
>>> js.foo(1, 'hi')
'foo(1, "hi", 3)'
>>> js.prop('up')
'func.assigned.to.nested.prop("up")'
