ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
@solid-primitives/utils
Advanced tools
A bunch of reactive utility types and functions, for building primitives with Solid.js
Solid Primitives Utilities is a support and helper package for a number of primitives in our library. Please free to augment or centralize useful utilities and methods in this package for sharing.
npm install @solid-primitives/utils
# or
pnpm add @solid-primitives/utils
# or
yarn add @solid-primitives/utils
Functional programming helpers for making non-mutating changes to data. Keeping it immutable. Useful for updating signals.
import { pick } from "@solid-primitives/utils/immutable";
const original = { foo: 123, bar: "baz" };
const newObj = pick(original, "foo");
original; // { foo: 123, bar: "baz" }
newObj; // { foo: 123 }
Use it for changing signals:
import { push, update } from "@solid-primitives/utils/immutable";
const [list, setList] = createSignal([1, 2, 3]);
setList(p => push(p, 4));
const [user, setUser] = createSignal({
name: "John",
street: { name: "Kingston Cei", number: 24 },
});
setUser(p => update(p, "street", "number", 64));
