valid-lazy
==========
Ensures that definitions and uses of properties on the ``lazy`` object are valid.
This rule checks for using unknown properties, duplicated symbols, unused
symbols, and also lazy getter used at top-level unconditionally.
Examples of incorrect code for this rule:
-----------------------------------------
.. code-block:: js
const lazy = {};
if (x) {
// Unknown lazy member property {{name}}
lazy.bar.foo();
}
.. code-block:: js
const lazy = {};
XPCOMUtils.defineLazyGetter(lazy, "foo", "foo.jsm");
// Duplicate symbol foo being added to lazy.
XPCOMUtils.defineLazyGetter(lazy, "foo", "foo1.jsm");
if (x) {
lazy.foo3.bar();
}
.. code-block:: js
const lazy = {};
// Unused lazy property foo
XPCOMUtils.defineLazyGetter(lazy, "foo", "foo.jsm");
.. code-block:: js
const lazy = {};
XPCOMUtils.defineLazyGetter(lazy, "foo", "foo.jsm");
// Used at top-level unconditionally.
lazy.foo.bar();
Examples of correct code for this rule:
---------------------------------------
.. code-block:: js
const lazy = {};
XPCOMUtils.defineLazyGetter(lazy, "foo1", () => {});
XPCOMUtils.defineLazyModuleGetters(lazy, { foo2: "foo2.jsm" });
if (x) {
lazy.foo1.bar();
lazy.foo2.bar();
}
