javascript programming web frontend react

shared by 張 旭 on 23 Jan 17 - No Cached
  • React 起源于 Facebook 的内部项目，因为该公司对市场上所有 JavaScript MVC 框架，都不满意，就决定自己写一套，用来架设 Instagram 的网站。
  • 项目本身也越滚越大，从最早的UI引擎变成了一整套前后端通吃的 Web App 解决方案
  • React Native 项目，目标更是宏伟，希望用写 Web App 的方式去写 Native App。
  • ...9 more annotations...
  • 凡是使用 JSX 的地方，都要加上 type="text/babel"
  • Browser.js 的作用是将 JSX 语法转为 JavaScript 语法，这一步很消耗时间，实际上线的时候，应该将它放到服务器完成。
  • HTML 语言直接写在 JavaScript 语言之中，不加任何引号，这就是 JSX 的语法，它允许 HTML 与 JavaScript 的混写
  • JSX 的基本语法规则：遇到 HTML 标签（以 < 开头），就用 HTML 规则解析；遇到代码块（以 { 开头），就用 JavaScript 规则解析。
  • JSX 允许直接在模板插入 JavaScript 变量。如果这个变量是一个数组，则会展开这个数组的所有成员
  • 所有组件类都必须有自己的 render 方法，用于输出组件
  • 组件类的第一个字母必须大写，否则会报错
  • 组件类只能包含一个顶层标签
  • 添加组件属性，有一个地方需要注意，就是 class 属性需要写成 className ，for 属性需要写成 htmlFor ，这是因为 class 和 for 是 JavaScript 的保留字。

    "歡迎光臨！本書將會讓你學會 Rust 程式語言。 Rust 是個專注在三項目標的系統程式語言：安全、速度、及並行（concurrency）。 它無需透過垃圾回收機制去達成以上目標，這使它成為一種能在其他語言不擅長的方面大展身手的程式語言，例如：嵌入到其他語言中、在特定空間及時間的限制下撰寫程式、撰寫硬體驅動程式和作業系統之類的底層程式碼。 它透過某些在執行期不會產生額外負擔的編譯期安全檢查，去增進現有程式語言的目標，並去除所有的資料競爭（data races）。 Rust 同時也旨在實現「無成本抽象化」（zero-cost abstractions），雖然，有些抽象化讓他看起來像是高階語言。 即便如此，Rust 仍允許像低階語言一樣進行精確控制。 "

raft algorithm algorithms consensus

shared by crazylion lee on 10 Jun 16 - No Cached
  • crazylion lee on 10 Jun 16
     
    " Raft is a consensus algorithm that is designed to be easy to understand. It's equivalent to Paxos in fault-tolerance and performance. The difference is that it's decomposed into relatively independent subproblems, and it cleanly addresses all major pieces needed for practical systems. We hope Raft will make consensus available to a wider audience, and that this wider audience will be able to develop a variety of higher quality consensus-based systems than are available today."

Serverless Architectures - 0 views

development architecture system server backend

shared by 張 旭 on 12 Jul 16 - No Cached
  • Serverless was first used to describe applications that significantly or fully depend on 3rd party applications / services (‘in the cloud’) to manage server-side logic and state.
  • ‘rich client’ applications (think single page web apps, or mobile apps) that use the vast ecosystem of cloud accessible databases (like Parse, Firebase), authentication services (Auth0, AWS Cognito), etc.
  • ‘(Mobile) Backend as a Service’
  • ...33 more annotations...
  • Serverless can also mean applications where some amount of server-side logic is still written by the application developer but unlike traditional architectures is run in stateless compute containers that are event-triggered, ephemeral (may only last for one invocation), and fully managed by a 3rd party.
  • ‘Functions as a service
  • AWS Lambda is one of the most popular implementations of FaaS at present,
  • A good example is Auth0 - they started initially with BaaS ‘Authentication as a Service’, but with Auth0 Webtask they are entering the FaaS space.
  • a typical ecommerce app
  • a backend data-processing service
  • with zero administration.
  • FaaS offerings do not require coding to a specific framework or library.
  • Horizontal scaling is completely automatic, elastic, and managed by the provider
  • Functions in FaaS are triggered by event types defined by the provider.
  • a FaaS-supported message broker
  • from a deployment-unit point of view FaaS functions are stateless.
  • allowed the client direct access to a subset of our database
  • deleted the authentication logic in the original application and have replaced it with a third party BaaS service
  • The client is in fact well on its way to becoming a Single Page Application.
  • implement a FaaS function that responds to http requests via an API Gateway
  • port the search code from the Pet Store server to the Pet Store Search function
  • replaced a long lived consumer application with a FaaS function that runs within the event driven context
  • server applications - is a key difference when comparing with other modern architectural trends like containers and PaaS
  • the only code that needs to change when moving to FaaS is the ‘main method / startup’ code, in that it is deleted, and likely the specific code that is the top-level message handler (the ‘message listener interface’ implementation), but this might only be a change in method signature
  • With FaaS you need to write the function ahead of time to assume parallelism
  • Most providers also allow functions to be triggered as a response to inbound http requests, typically in some kind of API gateway
  • you should assume that for any given invocation of a function none of the in-process or host state that you create will be available to any subsequent invocation.
  • FaaS functions are either naturally stateless
  • store state across requests or for further input to handle a request.
  • certain classes of long lived task are not suited to FaaS functions without re-architecture
  • if you were writing a low-latency trading application you probably wouldn’t want to use FaaS systems at this time
  • An API Gateway is an HTTP server where routes / endpoints are defined in configuration and each route is associated with a FaaS function.
  • API Gateway will allow mapping from http request parameters to inputs arguments for the FaaS function
  • API Gateways may also perform authentication, input validation, response code mapping, etc.
  • the Serverless Framework makes working with API Gateway + Lambda significantly easier than using the first principles provided by AWS.
  • Apex - a project to ‘Build, deploy, and manage AWS Lambda functions with ease.'
  • 'Serverless' to mean the union of a couple of other ideas - 'Backend as a Service' and 'Functions as a Service'.
