Guia abrangente para escrever scripts shell com Google zx — uma ferramenta para criar scripts melhores usando JavaScript/TypeScript. Use ao escrever, depurar ou refatorar scripts zx (.mjs, .js, .ts usando zx), executar comandos shell do JavaScript, trabalhar com APIs ProcessPromise/ProcessOutput, encadear streams, configurar opções do zx ou usar a CLI do zx. NÃO use para perguntas gerais sobre Node.js não relacionadas a scripts shell.

O que é openclaw-master-skills?

Esta skill fornece um guia completo para o Google zx, uma ferramenta que permite escrever scripts shell usando JavaScript/TypeScript, combinando o poder do ecossistema JavaScript com a conveniência de comandos shell. Ela é particularmente útil para desenvolvedores que precisam criar scripts de automação complexos, onde o Bash tradicional se torna difícil de manter. A skill aborda desde a instalação e conceitos básicos, como o uso de templates literais com `$`...` para executar comandos com escape automático de argumentos, até tópicos avançados como execução paralela, tratamento de erros com `nothrow`, encadeamento de streams (`pipe`), iteração assíncrona, e configuração de shell (bash, PowerShell). Também documenta diversos helpers integrados como `cd()`, `fetch()`, `question()`, `retry()`, `spinner()`, e `glob()`, além de explicar como usar opções de configuração via `$({...})`, trabalhar com `ProcessPromise` e `ProcessOutput`, e utilizar pacotes npm expostos como `chalk`, `fs-extra`, `yaml`, e `minimist`. A skill é compatível com scripts `.mjs`, `.js` e `.ts`, e oferece múltiplas formas de execução: diretamente via `zx`, com `npx`, ou como loader do Node.js.

Documentação

Zx — Escreva Scripts Shell Melhores com JavaScript

Visão Geral

zx é a ferramenta do Google para escrever scripts shell em JavaScript/TypeScript. Ela encapsula child_process, faz escape automático de argumentos e fornece padrões sensatos — dando a você o poder do ecossistema JavaScript em seus scripts.

#!/usr/bin/env zx

await $`cat package.json | grep name`

const branch = await $`git branch --show-current`
await $`dep deploy --branch=${branch}`

const name = 'foo & bar'
await $`mkdir /tmp/${name}`  // Sem necessidade de aspas — escape automático

Bash é ótimo para tarefas simples, mas quando os scripts ficam complexos, uma linguagem de programação completa ajuda. zx adiciona encapsulamentos úteis ao redor de child_process, faz escape de argumentos e fornece padrões sensatos. Pense: bash + JavaScript em um único script.

Gatilhos

Também é acionado quando usuários perguntam sobre execução de comandos shell em JavaScript, conversão de scripts bash para zx, execução de scripts remotos, scripts Markdown ou scripts shell TypeScript.

Início Rápido

npm install zx

Escreva scripts como arquivos .mjs (suporta await de nível superior). Adicione o shebang #!/usr/bin/env zx ou execute via CLI:

zx ./script.mjs           # Execução direta
npx zx ./script.mjs       # Via npx
node --import zx/globals  # Como loader do Node.js

Todas as funções ($, cd, fetch, etc.) estão globalmente disponíveis em scripts zx sem necessidade de importação. Para importações explícitas (melhor autocompletar do VS Code):

import 'zx/globals'

Conceitos Principais

$`comando` — Execute Comandos Shell

O template literal com tag é o coração do zx. Tudo dentro de ${...} é escapado e entre aspas automaticamente.

// Assíncrono (padrão) — retorna ProcessPromise
const output = await $`ls -la`

// Variante síncrona — retorna ProcessOutput diretamente
const dir = $.sync`pwd`

// Arrays são achatados
const flags = ['--oneline', '--decorate', '--color']
await $`git log ${flags}`

// Códigos de saída diferentes de zero lançam ProcessOutput
try {
  await $`exit 1`
} catch (p) {
  console.log(`Exit: ${p.exitCode}, Error: ${p.stderr}`)
}

Configuração Predefinida com $({...})

Crie instâncias $ personalizadas com opções predefinidas — encadeáveis e combináveis:

const $$ = $({ verbose: false, env: { NODE_ENV: 'production' } })
const pwd = $$.sync`pwd`

// Predefinições são encadeáveis
const $1 = $({ nothrow: true })
const $2 = $1({ sync: true })  // Ambas as opções nothrow + sync aplicadas

ProcessPromise e ProcessOutput

Árvore de Decisão

Ao escrever scripts zx, use esta árvore de decisão:

ObjetivoAbordagem
Executar um comandoawait $`cmd`
Executar sincronamente$.sync`cmd`
Encadear saída.pipe($`proximo`) / .pipe('arquivo.txt')
Lidar com erros graciosamente$({nothrow: true}) / .nothrow()
Definir tempo limite$({timeout: '30s'}) / .timeout('30s')
Analisar saída JSON(await $`cmd`).json()
Streaming em tempo realfor await (const line of $`cmd`)
Repetir em caso de falharetry(5, () => $`cmd`)
Prompt para usuárioquestion('Nome: ')
Indicador de progressoawait spinner('Trabalhando...', () => $`cmd`)
Mudar diretóriocd('/caminho') ou within(() => { $.cwd = '/tmp' })
Arquivos/diretórios temporáriostmpfile() / tmpdir()
Analisar argumentos CLIargv.flag ou minimist(process.argv.slice(2))
Carregar arquivo .envdotenv.config('.env')

Escrevendo Scripts zx Eficazes

Execução Paralela

const results = await Promise.all([
  $`sleep 1; echo 1`,
  $`sleep 2; echo 2`,
  $`sleep 3; echo 3`,
])

Tratamento de Erros com nothrow

$.nothrow = true

const repos = ['zx', 'webpod']
const clones = repos.map(n => $`git clone https://github.com/google/${n}`)

const results = await Promise.all(clones)
const errors = results.filter(o => !o.ok).map(o => o.stderr.trim())
console.log('Erros:', errors.join('\n'))

Encadeamento de Streams

// Encadeie comandos como pipes do bash
const greeting = await $`printf "hello"`
  .pipe($`awk '{printf $1", world!"}'`)
  .pipe($`tr '[a-z]' '[A-Z]'`)

// Pipe para arquivo
await $`echo "Olá!"`.pipe('/tmp/saida.txt')

// Saída em tempo real para o terminal
await $`echo 1; sleep 1; echo 2; sleep 1; echo 3`.pipe(process.stdout)

Divisão e Mesclagem de Streams

// Dividir uma fonte para múltiplos consumidores
const p = $`algum-comando`
const [o1, o2] = await Promise.all([
  p.pipe`log`,
  p.pipe`extrair`,
])

// Mesclar múltiplas fontes
const $h = $({ halt: true })
const p1 = $`echo foo`
const p2 = $h`echo a && sleep 0.1 && echo b`
const p3 = $h`echo c && sleep 0.1 && echo d`
const cat = $h`cat`
p1.pipe(cat); p2.pipe(cat); p3.pipe(cat)
await cat.run()

Formatadores de Saída

const p = $`echo '{"foo":"bar"}\nline2'`

await p.json()    // { foo: 'bar' }
await p.lines()   // ['{"foo":"bar"}', 'line2']
await p.text()    // '{"foo":"bar"}\nline2\n'

Iteração Assíncrona

for await (const line of $`git log --oneline --max-count=5`) {
  console.log(line)
}

Configuração do Shell

O zx usa bash como padrão. Troque de shell conforme necessário:

import { useBash, usePowerShell, usePwsh } from 'zx'

usePowerShell()  // PowerShell.exe
usePwsh()        // PowerShell v7+
useBash()        // Voltar ao bash

// Substituição manual
$.shell = '/bin/zsh'

No Windows, considere usar WSL ou Git Bash para suporte a bash, ou mude para PowerShell via usePowerShell().
