Hey everyone! I’m building a Vue.js app that pulls data from an Airtable database. I need help with implementing a filtering feature.
Basically, I have a table containing course information with different subjects like chemistry, physics, and so on. Right now my app shows all records, but I want users to be able to filter and see only specific subjects.
For example, if someone selects “chemistry” from a dropdown, only those records should appear. Has anyone worked with similar functionality before? What’s the best approach to handle this kind of filtering?
Any suggestions would be really helpful!
I’ve done this exact thing multiple times. Keep your original data untouched and create a separate filtered array.
Set up a data property for your selected filter value, then use a computed property that returns the filtered results:
computed: {
filteredCourses() {
if (!this.selectedSubject) return this.allCourses
return this.allCourses.filter(course => course.subject === this.selectedSubject)
}
}
Bind your dropdown to the selectedSubject data property and render the filteredCourses instead of raw data. Vue handles reactivity automatically.
One thing I learned the hard way - make sure your Airtable field names are consistent. Mixed case or extra spaces will break your filtering logic.
This video shows a clean implementation:
The approach is solid and performs well even with larger datasets since computed properties are cached.
I used a watcher on the filter value plus computed properties when I built filtering for my Vue app with external data. It worked great. The trick is handling async Airtable requests properly. Set up your filter logic to work with whatever data structure Airtable sends back. Field names sometimes come back different than you’d expect, so I always add defensive coding for when the subject field is null or undefined. You’ll want to decide between client-side or server-side filtering. Client-side works fine for smaller datasets, but if you’ve got hundreds of records, use Airtable’s built-in filtering via their API to cut down payload size. The filterByFormula parameter handles subject filtering really efficiently. Pro tip: debounce the filter input if you’re planning to add text-based filtering later - helps with performance.
computed props are the way to go! just create a reactive prop for the selected subject, and then filter ur records in a computed func. the view will auto-update when users change their selection, making it super easy!
