Building a Music Step Sequencer with Vue.js
Getting Started
In this tutorial, we’ll explore the versatility of Vue.js by building a simple yet fully functional music step sequencer. We’ll combine Vue with Vuetify and howler.js to create an interactive app that allows users to create and save beats. Before we dive in, make sure you have Node.js, Vue, and Vue CLI installed on your machine.
Setting Up the Project
Create a new Vue project using Vue CLI, and add Vuetify and howler.js to the project. Clean up the default project by deleting unnecessary files and configuring the project structure.
Building the App Template
Create a base app template using Vuetify’s v-card and v-toolbar components. Add a title bar and a blank page to get started.
Adding Audio Functionality
Set up the base audio functionality by including four sound sample files (kick, snare, hi-hat, and shaker) and creating an instance of the audio context. Define properties for tempo, tracks, and playback control.
Creating the SoundTracks Component
Create a SoundTracks component to render the tracks. Pass a tracks prop to the component and define methods for playing and stopping sounds. Use Vuetify’s v-switch and v-button-toggle components to create interactive track controls.
Creating the SoundControls Component
Create a SoundControls component to handle playback, tempo, and metronome functionality. Pass props for tempo, counter, and isPlaying, and define methods for playing, stopping, and updating the tempo.
Creating the SoundPresets Component
Create a SoundPresets component to save and load beats presets. Define properties for currentPreset, dialog, presetName, and userPresets. Create methods for clearing tracks, loading presets, saving presets, and deleting presets.
Putting it All Together
Include the components in the app template and add event listeners to handle user interactions. Use Vue’s computed properties and watchers to update the app state.
Final Result
Congratulations! You’ve built a fully functional music step sequencer using Vue.js, Vuetify, and howler.js. This project demonstrates the versatility of Vue and its ability to integrate with other libraries to create complex applications.
Debugging and Monitoring
To take your Vue app to the next level, consider using LogRocket to monitor and track Vue mutations in production. LogRocket provides a comprehensive debugging experience, allowing you to aggregate and report on application state when issues occur.
