Here is a short practice to get started with Meteor.js:
- Create a new Meteor project by running the following command in your terminal:
luaCopy codemeteor create my-app
- Change into the directory for your new Meteor project:
bashCopy codecd my-app
- Start the Meteor development server by running the following command:
Copy codemeteor
- Open your web browser and visit http://localhost:3000 to view your new Meteor application.
- Modify the contents of the
my-app.html
file to change the layout of the application. For example, you can add a header and a footer to the page. - Add some data to the application using Meteor’s reactive data model. For example, you can create a collection of items that can be displayed in the user interface.
scssCopy codeif (Meteor.isClient) {
// Create a collection of items
Items = new Mongo.Collection("items");
// Add a helper function to retrieve the items from the collection
Template.body.helpers({
items: function () {
return Items.find({});
}
});
}
if (Meteor.isServer) {
// Add some items to the collection
Meteor.startup(function () {
if (Items.find().count() === 0) {
Items.insert({ name: "Item 1" });
Items.insert({ name: "Item 2" });
Items.insert({ name: "Item 3" });
}
});
}
- Use Meteor’s templates and events to add interactivity to the application. For example, you can add an event handler to delete items from the collection.
javascriptCopy codeif (Meteor.isClient) {
// Add an event handler to delete items
Template.body.events({
"click .delete": function () {
Items.remove(this._id);
}
});
}
This practice should give you a basic understanding of how to build applications with Meteor.js. With its fast and flexible architecture, Meteor is a great choice for building real-time web applications that can be run on both the client and the server.
