# API de contexto

Proveedores que necesitarás.

## Resumen

Esta sección mostrará el código para los providers que usaremos, como para pestañas, wallet y escrow. 

## Gestión global del estado de Pestañas

La gestión global del estado de las pestañas implica mantener y sincronizar el estado de los componentes de pestañas en toda la aplicación para asegurar coherencia y eficiencia.

```typescript
"use client";

import { createContext, useContext, useState, ReactNode } from "react";

type Tabs = "deploy" | "escrow" | "helper";

interface TabsContextType {
  activeTab: Tabs;
  setActiveTab: (tab: Tabs) => void;
}

const TabsContext = createContext<TabsContextType | undefined>(undefined);

export function useTabsContext() {
  const context = useContext(TabsContext);
  if (!context) {
    throw new Error("useTabsContext must be used within TabsProvider");
  }
  return context;
}

export function TabsProvider({ children }: { children: ReactNode }) {
  const [activeTab, setActiveTab] = useState<Tabs>("deploy");

  return (
    <TabsContext.Provider value={{ activeTab, setActiveTab }}>
      {children}
    </TabsContext.Provider>
  );
}

```

## Gestión global del estado de Escrow

La gestión global del estado de escrow implica manejar el estado relacionado con las funcionalidades de escrow dentro de una aplicación. Asegura que todos los componentes que interactúan con operaciones de escrow mantengan un estado sincronizado.

```typescript
"use client";

import { Escrow } from "@/@types/escrows/escrow.entity";
import { createContext, useContext, useState, ReactNode } from "react";

/**
 *
 * Escrow Context
 *
 */
interface EscrowContextProps {
  escrow: Escrow | null;
  setEscrow: (escrow: Escrow) => void;
  resetEscrow: () => void;
}

const EscrowContext = createContext<EscrowContextProps | undefined>(undefined);

/**
 * Escrow Provider
 *
 * @Note:
 * - Estamos usando useContext para proporcionar el escrow único en todo el proyecto. Pero en tu caso, tú
 *   puedes usar Redux o Zustand para almacenar el escrow.
 *
 */
export const EscrowProvider = ({ children }: { children: ReactNode }) => {
  const [escrow, setEscrowState] = useState<Escrow | null>(null);

  /**
   * Set Escrow
   *
   * @param newEscrow - New escrow
   */
  const setEscrow = (newEscrow: Escrow) => {
    setEscrowState(newEscrow);
  };

  /**
   * Reset Escrow
   */
  const resetEscrow = () => {
    setEscrowState(null);
  };

  return (
    <EscrowContext.Provider value={{ escrow, setEscrow, resetEscrow }}>
      {children}
    </EscrowContext.Provider>
  );
};

export const useEscrowContext = () => {
  const context = useContext(EscrowContext);
  if (!context) {
    throw new Error("useEscrowContext must be used within EscrowProvider");
  }
  return context;
};

```

## Gestión global del estado de Wallet

La gestión global del estado de la wallet asegura el manejo consistente de los estados relacionados con la wallet en toda la aplicación.

```typescript
"use client";

import {
  createContext,
  useContext,
  useState,
  useEffect,
  ReactNode,
} from "react";

type WalletContextType = {
  walletAddress: string | null;
  walletName: string | null;
  setWalletInfo: (address: string, name: string) => void;
  clearWalletInfo: () => void;
};

const WalletContext = createContext<WalletContextType | undefined>(undefined);

export const WalletProvider = ({ children }: { children: ReactNode }) => {
  const [walletAddress, setWalletAddress] = useState<string | null>(null);
  const [walletName, setWalletName] = useState<string | null>(null);

  // Cargar o establecer información de la wallet desde localStorage
  useEffect(() => {
    const storedAddress = localStorage.getItem("walletAddress");
    const storedName = localStorage.getItem("walletName");

    if (storedAddress) setWalletAddress(storedAddress);
    if (storedName) setWalletName(storedName);
  }, []);

  /**
   * Set wallet info
   *
   * @param address - Wallet address
   * @param name - Wallet name
   */
  const setWalletInfo = (address: string, name: string) => {
    setWalletAddress(address);
    setWalletName(name);
    localStorage.setItem("walletAddress", address);
    localStorage.setItem("walletName", name);
  };

  /**
   * Clear wallet info
   */
  const clearWalletInfo = () => {
    setWalletAddress(null);
    setWalletName(null);
    localStorage.removeItem("walletAddress");
    localStorage.removeItem("walletName");
  };

  return (
    <WalletContext.Provider
      value={{ walletAddress, walletName, setWalletInfo, clearWalletInfo }}
    >
      {children}
    </WalletContext.Provider>
  );
};

export const useWalletContext = () => {
  const context = useContext(WalletContext);
  if (!context) {
    throw new Error("useWalletContext must be used within WalletProvider");
  }
  return context;
};

```

## Global Provider

Construimos un provider global para gestionar los providers.

```typescript
import { EscrowProvider } from "./escrow.provider";
import { WalletProvider } from "./wallet.provider";
import { TabsProvider } from "./tabs.provider";

export const GlobalProvider = ({ children }: { children: React.ReactNode }) => {
  return (
    <WalletProvider>
      <TabsProvider>
        <EscrowProvider>{children}</EscrowProvider>
      </TabsProvider>
    </WalletProvider>
  );
};

```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.trustlesswork.com/trustless-work/v1-es/dapps-oss/escrow-lab/api-de-contexto.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
