Hi! Finally someone uploading videos related to firebase v9. Can u upload a version about data validation using firebase? for instance if i submit a form, and in that form if the ID number already exists, then my form should throw an error

[@maskman4821]

you should implement this logic yourself, you know what I am saying 🤔

[@maskman4821]

Take Shaun's latest released Reactjs course, you can find the solotions you are asking 😃

[@MrCuteguylol]

@@maskman4821 actually i didnt want this logic on frontend. And i dont know backend programming. Logic is actually fairly simple but i wanted to use backend programming for this

[@MrCuteguylol]

@@maskman4821 and thanks for the recommendation!

[@simionandrei5409]

Nice video! Is it a way to pass as an argument a variable? I want to look like this: where(''userID", "==", userID), where userID variable comes as a props withing my component.

[@danielwatson6529]

did u find the answer?

[@jsricochet]

@@danielwatson6529 I did that by creating a Search component (in React): import { useState } from 'react'; export default function Search({ handleSearch }) { const [searchTerms, setSearchTerms] = useState(''); return ( setSearchTerms(e.target.value)} placeholder='search terms' /> handleSearch(searchTerms)}>search ); } And then by using this Search component in App.jsx: async function handleSearch(searchTerms) { console.log(searchTerms); const searchQuery = query(colRef, where('technoName', '==', searchTerms)); const searchSnapshot = await getDocs(searchQuery); searchSnapshot.forEach((doc) => { console.log(doc.id, ' => ', doc.data()); }); getTechnos(searchSnapshot); } function getTechnos(snapshot) { let result = []; snapshot.docs.forEach((doc) => { result = [...result, { ...doc.data(), id: doc.id }]; }); setTechnos(result); } Be careful: it is case sensitive. There is no contains or 'SQL Like' in Firestore.
