cerebral-url-scheme-compiler

0.5.3 verified Fri May 01 auth: no javascript deprecated

A URL scheme compiler for the Cerebral state management framework (deprecated). Version 0.5.3 is the last release. It compiles path URLs into efficient getter and setter functions used by Cerebral actions. The package is deprecated due to Cerebral's evolution to v2+, which uses a different state access pattern. No longer maintained; alternatives include direct state access via Cerebral's props or other state libraries.

Common errors

error Cannot find module 'cerebral-url-scheme-compiler/get' ↓

cause Subpath import requires Node.js >=12 or specific bundler configuration.

fix

Ensure your environment supports package exports or use a bundler that resolves subpath imports.

error TypeError: getCompiler is not a function ↓

cause Incorrect import: importing from root package instead of subpath.

fix

Use import getCompiler from 'cerebral-url-scheme-compiler/get' instead of from 'cerebral-url-scheme-compiler'.

Warnings

deprecated Package is deprecated and no longer maintained. Use with Cerebral v2+ is not supported. ↓

fix Migrate to Cerebral v2+ which uses a different state access pattern via props or template literals.

breaking The package relies on Cerebral's internal state structure which changed significantly in v2. ↓

fix Do not use with Cerebral v2+; consider alternatives like direct object path access.

Imports

getCompiler

wrong

import { getCompiler } from 'cerebral-url-scheme-compiler'

correct

import getCompiler from 'cerebral-url-scheme-compiler/get'

Default export from a subpath; named export from root does not exist.

setCompiler

wrong

import { setCompiler } from 'cerebral-url-scheme-compiler'

correct

import setCompiler from 'cerebral-url-scheme-compiler/set'

Default export from a subpath; named export from root does not exist.

require('cerebral-url-scheme-compiler/get')
wrong
```
const getCompiler = require('cerebral-url-scheme-compiler').getCompiler
```
correct
```
const getCompiler = require('cerebral-url-scheme-compiler/get')
```
CommonJS require accesses the module's exports, which is the default function; there is no .getCompiler property on the root package.

Quickstart

Shows how to compile a URL path into a getter function and use it with a Cerebral controller.

import getCompiler from 'cerebral-url-scheme-compiler/get';
import { Controller, Module } from 'cerebral';
const app = Module({});
const controller = Controller(app);
const getValue = getCompiler('app.items.0.title');
const result = getValue({ state: controller.getState });
