- The CLI provides some cool features for customizing new projects, prototyping, adding plugins and checking out your Webpack config without no-going-back ejecting.
- One of my personal favorites is the CLI, which provides some cool features for customizing new projects, prototyping, adding plugins and checking out your Webpack config without no-going-back ejecting.
- As with the Angular and React (create-react-app) CLIs, Vue’s CLI makes it easy to create new apps.
- The beauty of Vue is that you could create an HTML file, add a script tag for Vue and start coding, but the Vue CLI has a feature that’s even faster, and which includes a dev server for running your prototypes.
- Much like create-react-app, the Vue CLI creates an abstraction around Webpack that enables you to use features and dependencies without manually modifying the Webpack config.
- One of the great features of Vue.js is that you can easily access data properties, computed properties and methods as this.vueProperty from within the context of the Vue configuration object.
- In the fitlerBySize computed property, we need to declare a variable size so this value can be used in the filter callback: – An arrow function uses the this object from the enclosing context.
- In this case, it’s from the filterBySize computed property, which has the Vue object bound to this, which simplifies the filter callback: – GotchaWhile arrow functions can be used effectively in many situations, it doesnt mean we should use them all the time when developing Vue.
- For example: – Vuex provides the mapState function which returns an object with all the Vuex state properties that you specify by providing their keys: – Using mapState in conjunction with the spread operator, we can combine local computed properties with those from Vuex in a very succinct way: -…
- If we just want to read a text file in order to do something trivial with it at the UI level, we dont need to send the file to the server.
- The FileReader API gives a nice interface to read data in different ways using the File or Blob object types.
- The FileReader instance has a method that we can use to read a file as text: – – Since the FileReader API is asynchronous, it exposes several events that we can use to get its state.
- In particular, well need the event to access the data when the file has been read: – – As you can see, the text data is accessible via .
- For that, we must use an HTML tag, that triggers a event where we can access the file via .
