fn update(model, msg) {
  case msg {
    Incr -> model + 1
    Decr -> model - 1
  }
}

fn view(model) {
  div([], [
    button([on_click(Incr)], [text(" + ")]),
    p([], [text(int.to_string(model))]),
    button([on_click(Decr)], [text(" - ")])
  ])
}

运行开发服务器：

gleam run -m lustre_dev_tools

核心概念：理解Lustre的MUV架构

Lustre采用了与Elm相似的架构，基于三个核心部分：Model（模型）、Update（更新）和View（视图），形成了简洁而强大的单向数据流。

数据流架构

MUV架构详解

组件	作用	类比React
Model	保存应用状态的数据结构	State/Context
Msg	描述状态变化的消息类型	Actions/Events
Update	根据Msg更新Model的纯函数	Reducer
View	将Model转换为UI的纯函数	Render函数

核心类型定义

// Model - 应用状态
type Model { Model(count: Int, todos: List(Todo)) }

// Msg - 状态变更消息
type Msg {
  Increment
  Decrement
  AddTodo(String)
  ToggleTodo(Int)
}

// Update - 状态更新函数
fn update(model: Model, msg: Msg) -> Model {
  case msg {
    Increment -> Model(..model, count: model.count + 1)
    Decrement -> Model(..model, count: model.count - 1)
    // 其他消息处理...
  }
}

// View - UI渲染函数
fn view(model: Model) -> Element(Msg) {
  html.div([], [
    html.h1([], [text("Lustre App")]),
    html.p([], [text("Count: " <> int.to_string(model.count))]),
    // 其他UI元素...
  ])
}

组件开发：构建可复用的UI单元

Lustre的组件系统基于Web Components API，允许创建封装的、可复用的UI单元。

基础组件结构

import lustre
import lustre/attribute
import lustre/component
import lustre/element
import lustre/element/html

// 组件配置
fn counter_config() -> component.Config(Msg) {
  component.new([
    component.on_property_change("value", decode.int),
    component.on_context_change("theme", decode.string),
  ])
}

// 组件状态
type Model { Model(count: Int) }

// 组件消息
type Msg { Increment | Decrement }

// 初始化函数
fn init(_) -> #(Model, effect.Effect(Msg)) {
  #(Model(0), effect.none())
}

// 更新函数
fn update(model: Model, msg: Msg) -> #(Model, effect.Effect(Msg)) {
  case msg {
    Increment -> #(Model(model.count + 1), effect.none())
    Decrement -> #(Model(model.count - 1), effect.none())
  }
}

// 视图函数
fn view(model: Model) -> element.Element(Msg) {
  html.div([], [
    html.button([event.on_click(Decrement)], [text("-")]),
    html.span([], [text(int.to_string(model.count))]),
    html.button([event.on_click(Increment)], [text("+")]),
  ])
}

// 注册组件
pub fn register() {
  lustre.register_component(
    "my-counter",
    counter_config(),
    init,
    update,
    view,
  )
}

组件属性与事件

// 使用组件
fn app_view() -> element.Element(Msg) {
  html.div([], [
    element(
      "my-counter",
      [
        attribute.property("value", 5),
        attribute.on("count-change", CountChanged),
      ],
      [],
    ),
  ])
}

// 处理组件事件
type Msg { CountChanged(Int) }

fn update(model: Model, msg: Msg) -> Model {
  case msg {
    CountChanged(value) -> Model(..model, last_count: value)
  }
}

插槽与内容分发

// 带插槽的组件视图
fn view(model: Model) -> element.Element(Msg) {
  html.div([], [
    component.named_slot("header", [], [html.h3([], [text("默认标题")])]),
    html.div([], [text("计数器: " <> int.to_string(model.count))]),
    component.default_slot([], [html.p([], [text("默认内容")])]),
  ])
}

// 使用带插槽的组件
fn app_view() -> element.Element(Msg) {
  element(
    "my-counter",
    [],
    [
      html.div([component.slot("header")], [html.h2([], [text("自定义标题")])]),
      html.p([], [text("这是自定义内容")]),
    ],
  )
}

组件样式封装

fn view(model: Model) -> element.Element(Msg) {
  html.fragment([
    html.style([], [
      text("""
        :host { display: flex; gap: 1rem; }
        button { padding: 0.5rem 1rem; }
        .count { font-size: 1.2rem; }
      """)
    ]),
    html.button([event.on_click(Decrement)], [text("-")]),
    html.span([attribute.class("count")], [text(int.to_string(model.count))]),
    html.button([event.on_click(Increment)], [text("+")]),
  ])
}

路由管理：实现单页应用导航

使用modem库实现客户端路由，管理应用的不同页面。

路由配置

import gleam/uri
import modem
import lustre/effect
import lustre/element/html

// 路由定义
type Route {
  Home
  Posts
  PostById(id: Int)
  About
  NotFound(uri: Uri)
}

// 解析路由
fn parse_route(uri: Uri) -> Route {
  case uri.path_segments(uri.path) {
    [] | [""] -> Home
    ["posts"] -> Posts
    ["post", post_id] ->
      case int.parse(post_id) {
        Ok(id) -> PostById(id)
        Error(_) -> NotFound(uri)
      }
    ["about"] -> About
    _ -> NotFound(uri)
  }
}

// 生成链接
fn href(route: Route) -> attribute.Attribute(msg) {
  let path = case route {
    Home -> "/"
    Posts -> "/posts"
    PostById(id) -> "/post/" <> int.to_string(id)
    About -> "/about"
    NotFound(_) -> "/404"
  }
  attribute.href(path)
}

路由初始化与处理

// 初始化路由
fn init() -> #(Model, effect.Effect(Msg)) {
  let route = case modem.initial_uri() {
    Ok(uri) -> parse_route(uri)
    Error(_) -> Home
  }
  
  let model = Model(route: route, posts: dict.new())
  
  let effect = effect.batch([
    modem.init(fn(uri) { parse_route(uri) |> UrlChanged }),
    fetch_posts(),
  ])
  
  #(model, effect)
}

// 处理路由变化
type Msg {
  UrlChanged(Route)
  // 其他消息...
}

fn update(model: Model, msg: Msg) -> #(Model, effect.Effect(Msg)) {
  case msg {
    UrlChanged(route) -> 
      #(Model(..model, route: route), load_route_data(route))
    // 其他消息处理...
  }
}

// 根据路由加载数据
fn load_route_data(route: Route) -> effect.Effect(Msg) {
  case route {
    Posts -> fetch_posts()
    PostById(id) -> fetch_post(id)
    _ -> effect.none()
  }
}

路由视图渲染

// 应用视图
fn view(model: Model) -> element.Element(Msg) {
  html.div([], [
    view_header(model.route),
    view_content(model),
    view_footer(),
  ])
}

// 头部导航
fn view_header(current_route: Route) -> element.Element(Msg) {
  html.nav([], [
    html.ul([], [
      view_nav_item(Home, current_route, "首页"),
      view_nav_item(Posts, current_route, "文章"),
      view_nav_item(About, current_route, "关于"),
    ])
  ])
}

// 导航项
fn view_nav_item(
  route: Route, 
  current_route: Route, 
  label: String
) -> element.Element(Msg) {
  let is_active = current_route == route
  
  html.li([], [
    html.a(
      [
        href(route),
        attribute.classes([
          #("nav-link", True),
          #("active", is_active),
        ]),
      ],
      [html.text(label)]
    )
  ])
}

// 内容区域
fn view_content(model: Model) -> element.Element(Msg) {
  case model.route {
    Home -> view_home()
    Posts -> view_posts(model.posts)
    PostById(id) -> view_post(model.posts, id)
    About -> view_about()
    NotFound(uri) -> view_not_found(uri)
  }
}

表单处理：受控组件与数据验证

Lustre提供了强大的表单处理能力，支持受控组件和声明式验证。

受控表单组件

import formal/form
import lustre/element/html
import lustre/event

// 表单数据类型
type LoginData { LoginData(username: String, password: String) }

// 创建表单
fn new_login_form() -> form.Form(LoginData) {
  form.new({
    use username <- form.field(
      "username",
      form.parse_string |> form.check_not_empty,
    )
    
    let check_password = fn(password) {
      case string.length(password) >= 8 {
        True -> Ok(password)
        False -> Error("密码长度不能少于8个字符")
      }
    }
    
    use password <- form.field(
      "password",
      form.parse_string |> form.check(check_password),
    )
    
    form.success(LoginData(username:, password:))
  })
}

// 表单视图
fn view_login(form: form.Form(LoginData)) -> element.Element(Msg) {
  let handle_submit = fn(values) {
    form |> form.add_values(values) |> form.run |> LoginSubmitted
  }
  
  html.form([event.on_submit(handle_submit)], [
    html.div([], [
      html.label([], [text("用户名")]),
      html.input([
        attribute.type_("text"),
        attribute.name("username"),
      ]),
      show_errors(form.field_errors(form, "username")),
    ]),
    
    html.div([], [
      html.label([], [text("密码")]),
      html.input([
        attribute.type_("password"),
        attribute.name("password"),
      ]),
      show_errors(form.field_errors(form, "password")),
    ]),
    
    html.button([], [text("登录")]),
  ])
}

// 显示错误信息
fn show_errors(errors: List(String)) -> element.Element(Msg) {
  case errors {
    [] -> element.none()
    _ -> html.ul([attribute.class("errors")], [
      for (error) in errors {
        html.li([attribute.class("error")], [text(error)])
      }
    ])
  }
}

表单状态管理

// 模型中的表单状态
type Model {
  LoginForm(form.Form(LoginData))
  LoggedIn(User)
  Error(String)
}

// 初始化表单
fn init() -> Model {
  LoginForm(new_login_form())
}

// 处理表单提交
type Msg {
  LoginSubmitted(Result(LoginData, form.Form(LoginData)))
  LoginSuccess(User)
  LoginError(String)
}

fn update(model: Model, msg: Msg) -> #(Model, effect.Effect(Msg)) {
  case msg {
    LoginSubmitted(Ok(data)) ->
      #(model, login(data.username, data.password))
    
    LoginSubmitted(Error(form)) ->
      #(LoginForm(form), effect.none())
    
    LoginSuccess(user) ->
      #(LoggedIn(user), effect.batch([
        store_user_session(user),
        effect.from(fn(dispatch) {
          dispatch(UrlChanged(Home))
        }),
      ]))
    
    LoginError(message) ->
      #(Error(message), effect.none())
  }
}

// 登录API调用
fn login(username: String, password: String) -> effect.Effect(Msg) {
  let url = "/api/login"
  let body = json.object([
    #("username", json.string(username)),
    #("password", json.string(password)),
  ])
  
  rsvp.post(
    url,
    [header("Content-Type", "application/json")],
    json.to_string(body),
    rsvp.expect_json(
      decode.map(
        user_decoder(),
        LoginSuccess,
        LoginError,
      ),
    ),
  )
}

服务器组件：打造全栈渲染体验

Lustre的服务器组件允许在服务器上渲染组件，并通过WebSocket与客户端保持同步。

服务器组件结构

import lustre
import lustre/server_component
import mist
import gleam/http/request
import gleam/http/response

// 服务器组件入口
pub fn main() {
  let assert Ok(_) =
    fn(req: request.Request(mist.Connection)) -> response.Response(mist.ResponseData) {
      case request.path_segments(req) {
        [] -> serve_html()
        ["runtime.mjs"] -> serve_runtime()
        ["ws"] -> serve_component(req)
        _ -> response.new(404)
      }
    }
    |> mist.new
    |> mist.port(3000)
    |> mist.start
  
  process.sleep_forever()
}

// 提供HTML页面
fn serve_html() -> response.Response(mist.ResponseData) {
  let html = html.html([], [
    html.head([], [
      html.script([
        attribute.type_("module"),
        attribute.src("/runtime.mjs"),
      ], []),
    ]),
    html.body([], [
      server_component.element([server_component.route("/ws")], []),
    ]),
  ])
  
  response.new(200)
  |> response.set_header("Content-Type", "text/html")
  |> response.set_body(mist.Bytes(html.to_bytes()))
}

// 提供客户端运行时
fn serve_runtime() -> response.Response(mist.ResponseData) {
  mist.send_file(
    "priv/static/lustre-server-component.mjs",
  )
}

服务器组件通信

// WebSocket处理
fn serve_component(req: request.Request(mist.Connection)) -> response.Response(mist.ResponseData) {
  mist.websocket(
    request: req,
    on_init: init_component,
    handler: handle_message,
    on_close: close_component,
  )
}

// 组件初始化
fn init_component(_) -> #(State, effect.Effect(Msg)) {
  let component = counter.component()
  let assert Ok(runtime) = lustre.start_server_component(component, Nil)
  
  #(State(runtime: runtime), effect.none())
}

// 消息处理
fn handle_message(
  state: State,
  msg: mist.WebsocketMessage,
  conn: mist.WebsocketConnection,
) -> mist.Next(State) {
  case msg {
    mist.Text(data) ->
      case json.parse(data, server_component.message_decoder()) {
        Ok(msg) -> 
          lustre.send(state.runtime, msg)
          mist.continue(state)
        Error(_) -> mist.continue(state)
      }
    _ -> mist.continue(state)
  }
}

状态管理：处理异步操作与副作用

Lustre通过Effect类型统一处理所有副作用，包括API调用、定时器和DOM操作。

副作用处理基础

import lustre/effect
import rsvp  // HTTP客户端库

// 无副作用
fn no_effect() -> effect.Effect(Msg) {
  effect.none()
}

// 基本副作用
fn log_message(message: String) -> effect.Effect(Msg) {
  effect.from(fn(dispatch) {
    io.println(message)
  })
}

// 带回调的副作用
fn delayed_message(ms: Int, msg: Msg) -> effect.Effect(Msg) {
  effect.from(fn(dispatch) {
    let timer = set_timeout(fn() { dispatch(msg) }, ms)
    effect.from(fn(_) { clear_timeout(timer) })
  })
}

HTTP请求处理

// 获取文章列表
fn fetch_posts() -> effect.Effect(Msg) {
  let url = "https://api.example.com/posts"
  
  rsvp.get(
    url,
    rsvp.expect_json(
      decode.list(post_decoder()),
      fn(result) {
        case result {
          Ok(posts) -> PostsFetched(posts)
          Error(e) -> FetchError("posts", e)
        }
      },
    ),
  )
}

// 获取单篇文章
fn fetch_post(id: Int) -> effect.Effect(Msg) {
  let url = "https://api.example.com/posts/" <> int.to_string(id)
  
  rsvp.get(
    url,
    rsvp.expect_json(
      post_decoder(),
      fn(result) {
        case result {
          Ok(post) -> PostFetched(post)
          Error(e) -> FetchError("post", e)
        }
      },
    ),
  )
}

// 文章解码器
fn post_decoder() -> decode.Decoder(Post) {
  use id <- decode.field("id", decode.int)
  use title <- decode.field("title", decode.string)
  use body <- decode.field("body", decode.string)
  use author <- decode.field("author", user_decoder())
  
  decode.success(Post(
    id: id,
    title: title,
    body: body,
    author: author,
  ))
}

复杂副作用组合

// 并行请求
fn load_dashboard_data() -> effect.Effect(Msg) {
  effect.batch([
    fetch_posts(),
    fetch_comments(),
    fetch_notifications(),
  ])
}

// 串行请求
fn create_and_load_post(data: PostData) -> effect.Effect(Msg) {
  effect.from(fn(dispatch) {
    let url = "https://api.example.com/posts"
    
    rsvp.post(
      url,
      [header("Content-Type", "application/json")],
      json.to_string(encode_post_data(data)),
      rsvp.expect_json(
        decode.int,  // 假设API返回新创建的ID
        fn(result) {
          case result {
            Ok(id) ->
              dispatch(PostCreated(id))
              // 创建成功后获取完整文章
              fetch_post(id) |> effect.run(dispatch)
            Error(e) ->
              dispatch(PostCreateError(e))
          }
        },
      ),
    )
    |> effect.run(dispatch)
  })
}

// 乐观更新
fn toggle_todo_optimistic(id: Int) -> effect.Effect(Msg) {
  effect.batch([
    // 立即更新UI
    effect.from(fn(dispatch) {
      dispatch(ToggleTodoLocally(id))
    }),
    // 后台同步到服务器
    update_todo_on_server(id)
  ])
}

fn update_todo_on_server(id: Int) -> effect.Effect(Msg) {
  let url = "https://api.example.com/todos/" <> int.to_string(id)
  
  rsvp.patch(
    url,
    [header("Content-Type", "application/json")],
    json.to_string(json.object([#("completed", json.bool(true))])),
    rsvp.expect_json(
      decode.unit,
      fn(result) {
        case result {
          Ok(_) -> TodoUpdatedSuccess(id)
          Error(e) -> TodoUpdateFailed(id, e)
        }
      },
    ),
  )
}

核心功能实现

文章列表与分页

// 文章列表组件
fn view_posts(model: Model) -> element.Element(Msg) {
  html.div([attribute.class("posts-container")], [
    html.h1([], [text("文章列表")]),
    
    html.div([attribute.class("posts-list")], [
      for (post) in model.posts {
        view_post_card(post)
      }
    ]),
    
    html.div([attribute.class("pagination")], [
      html.button(
        [
          attribute.disabled(model.page == 1),
          event.on_click(LoadPage(model.page - 1)),
        ],
        [text("上一页")]
      ),
      html.span([], [text("第 " <> int.to_string(model.page) <> " 页")]),
      html.button(
        [
          attribute.disabled(model.page >= model.totalPages), 
          event.on_click(LoadPage(model.page + 1)),
        ],
        [text("下一页")]
      ),
    ])
  ])
}

// 文章卡片
fn view_post_card(post: Post) -> element.Element(Msg) {
  html.article([attribute.class("post-card")], [
    html.h2([], [
      html.a(
        [href(PostById(post.id))],
        [text(post.title)]
      )
    ]),
    html.div([attribute.class("post-meta")], [
      html.span([], [text(post.author.name)]),
      html.span([], [text(format_date(post.createdAt))]),
      html.div([attribute.class("tags")], [
        for (tag) in post.tags {
          html.span([attribute.class("tag")], [text(tag)])
        }
      ])
    ]),
    html.p([attribute.class("post-excerpt")], [
      text(first_paragraph(post.content))
    ]),
    html.a(
      [href(PostById(post.id)), attribute.class("read-more")],
      [text("阅读全文 →")]
    )
  ])
}

文章详情与评论

// 文章详情页
fn view_post_detail(model: Model) -> element.Element(Msg) {
  case model.current_post {
    None -> html.div([], [text("加载中...")])
    Some(post) -> html.article([attribute.class("post-detail")], [
      html.header([], [
        html.h1([], [text(post.title)]),
        html.div([attribute.class("post-meta")], [
          html.span([], [text(post.author.name)]),
          html.span([], [text(format_date(post.createdAt))]),
        ])
      ]),
      
      html.div([attribute.class("post-content")], [
        render_markdown(post.content)
      ]),
      
      html.section([attribute.class("comments")], [
        html.h2([], [text("评论 (" <> int.to_string(list.length(model.comments)) <> ")")]),
        
        if (model.user.is_some()) {
          comment_form(model.comment_form)
        } else {
          html.p([], [
            html.text("请 "),
            html.a([href(Login)], [text("登录")]),
            html.text(" 后发表评论")
          ])
        },
        
        html.div([attribute.class("comments-list")], [
          for (comment) in model.comments {
            view_comment(comment)
          }
        ])
      ])
    ])
  }
}

后台管理

// 文章编辑表单
fn post_editor(model: PostEditorModel) -> element.Element(Msg) {
  html.form([event.on_submit(SubmitPost)], [
    html.div([attribute.class("form-group")], [
      html.label([], [text("标题")]),
      html.input([
        attribute.type_("text"),
        attribute.name("title"),
        attribute.value(model.title),
        event.on_input(UpdateTitle),
      ])
    ]),
    
    html.div([attribute.class("form-group")], [
      html.label([], [text("内容")]),
      html.textarea([
        attribute.name("content"),
        attribute.value(model.content),
        event.on_input(UpdateContent),
        attribute.class("markdown-editor"),
      ])
    ]),
    
    html.div([attribute.class("form-group")], [
      html.label([], [text("标签 (用逗号分隔)")]),
      html.input([
        attribute.type_("text"),
        attribute.value(string.join(model.tags, ", ")),
        event.on_input(UpdateTags),
      ])
    ]),
    
    html.div([attribute.class("form-actions")], [
      html.button(
        [attribute.type_("button"), event.on_click(CancelEdit)],
        [text("取消")]
      ),
      html.button(
        [attribute.type_("submit")],
        [text(if model.is_new { "创建" } else { "更新" })]
      )
    ])
  ])
}
