- It allows the user to type in a specific product name, to crawl multiple e-commerce sites and asynchronously return useful results to the user.
- UI and ArchitectureBuilding the front endTo make it short, the front end is really small (only two pages: one for the search box and another one for the results).
- I moved everything from ‘search term’ to ‘search results items’ into Redux’s state, thus making the code structure cleaner and nicer.
- Some other problematic factors include: – Not having pre-stored information that could be useful to make predictions.Each result item consisting only of the following data: title, price, URL and thumbnail.My conclusion was to use a weighted ranking algorithm.
- In a more complete implementation, that data could be useful for some sort of Machine Learning algorithm to predict the most useful way to rank results.
This is a quick story about how I created a simple but end-to-end e-commerce scraping web application called “crawl-io”. The goal behind this article is to provide an example of an implementation so…

- I’ve created two nearly identical sample applications, one in Vue and one in React, if you’d like to give either framework a shot in the context of the samples in this article.
- Both React and Vue are focused solely on the UI layer, and leave functionality such as routing and state handling to companion frameworks.
- In Vue there’s no need to call a state management function like , as the data parameter on the Vue object acts as the holder for application data.
- Horizon, which is built on RethinkDB and by the RethinkDB team, facilitates common application development tasks like backend setup, real-time data transfer, security and scalability.
- This tutorial will give you an introduction to Horizon and RethinkDB while also showing you how to build a simple app with Horizon and React.
- Before hitting the code, let’s learn a few basic Horizon concepts:
Horizon groups data into horizon collections and each collection is backed by a RethinkDB table.
- Here’s a visual to help you make sense of the data flow in this app:
Note that any change in the data is sent from one React client into Horizon and Horizon sends it back to all React apps so they can update their view, this flow makes sure that all clients are always watching the same without inconsistencies.
- Our app will use two Horizon collections, one for the “we need list” and other for the “we have list”.
Horizon is an open source Backend as a Service (BaaS) that allows developers to easily build data-driven web and mobile applications. Horizon, which is built on RethinkDB and by the RethinkDB team, facilitates common application development tasks like backend setup, real-time data transfer, security and scalability. Horizon can be run locally, on a private server or in the cloud.

- Two weeks ago we changed our name from Exponent to Expo, and last week we shipped two projects that we have been working on for a few months!Create React Native AppOn Monday, March 13 2017 we announced Create React Native App at React Conf.
- You can read the announcement blog post over on the React Native blog, and check out the differences between create-react-native-app and Expo in our docs.
- Just like Create React Native App did last Monday, on Tuesday the Expo Sketch announcement blog post hit number 1 on Hacker News and remained on the front page all day (link to the post).
- So we wired up Discourse with our account system and launched it earlier this week.Go to https://forums.expo.io and sign in with your Expo account, then introduce yourself and let us know what you’re working 8 support has been dropped from ExpoAs we mentioned in the SDK14 release notes, with SDK15 we have dropped support for iOS 8, following the lead of apps like Twitter and Slack that did this months ago.According to Mixpanel Trends data, worldwide iOS 8 usage comes in at a total of 1.18 percent.
- If you depend on this, you should switch it out with a normal ScrollView.Upgrading your app to Expo SDK v15.0.0 from v14.0.0If you are still using exponent packages instead of expo, please follow the steps described in Updating your project for the Exponent → Expo name changeClose XDE or your exp CLI serverIn exp.json, change sdkVersion to “15.0.0”In package.json:- change react-native version to change expo version to “^15.0.2”- delete your project’s node_modules directory and run npm installagain.Re-open XDE or exp and start your project once npm install from the previous step has completed.Update the Expo app on your phones from the App Store / Play Store.
Expo SDK 15.0.0 is based on the recently released React Native
0.42.0, “February”. This is a jump of 1 version of React Native; Expo
SDK 14.0.0 was based off of 0.41.0, “January”. Two weeks ago we…

- Tools like Create React Native App and Expo make this much easier, but it’s still not quite the same experience as an online demo.I’ve been lucky enough to be working with Charlie Cheever and Jesse Ruder on Sketch for the past month, which addresses these pain points and makes it super easy to try something quickly.
- And today we’re excited to announce Sketch to the public.Let’s go over the features, shall we?Instantly test your code on a device, or in the browserCreating a new sketch couldn’t be easier.
- You can either preview the component on the emulator inside the browser, or open it directly on your device with the Expo app.The UI updates as you type — every keystroke, without having to hit save.
- Facebook Login, BarCode scanner, Accelerometer, Maps, you name it.You can also import the following third party modules which we’ve bundled with the app: @expo/vector-icons, @expo/ex-navigation, react-router-native, react-navigation, react-native-tab-view, redux, react-redux, redux-effex, redux-logger, redux-thunk, apollo-client, react-apollo, graphql-tag, ReactNativeART, art/morph/path, base-64, date-fns, gl-mat4, hsv2rgb, immutable, lodash, pubnub, regl, seamless-immutable, socket.io-client, three, url-parse, uuid-jsvalidatorDrag and drop components to add features instantlyDon’t remember how to use those APIs and too lazy to look it up and copy paste code (and fix the errors, cause you never manage get it right the first time)?
- Fear not, there’s a component library from where you can just drag and drop components to add a feature instantly!See Device logs in the EditorNeed to log that object to see why your code won’t work?
Today, we’re happy and excited to announce the release of Expo Sketch. You can try it right now by going to https://sketch.expo.io/ on your computer’s web browser. I’ve been always excited about…

- There are links to other applications using the component that you can use as a reference implementation.
- Explorer automatically runs a demo of each component in a “component playground,” allowing you to view the component’s integration and change its props to modify it in real time.
- Spotlight on Electrode Explorer – React Component Reuse Without the Hassle
- There are other important factors affecting component reusability, such as consistent structure and tooling across components and applications.
- For example, components can only be reused if they can be discovered.
One of the most frequently touted benefits of Facebook’s React library is that its component model encourages code reuse. On a large scale, this means sharing components across applications — for…
