Add Full-Text Search to a Nuxt E-commerce Store with Tigris Search & Netlify Functions
Search is a fundamental part of an application, especially when we build retail and e-commerce applications. Search provides your customers with a great shopping experience. This blog will demonstrate how Tigris makes it super easy to add real-time and full-text search to your application using the Tigris embedded search engine, which automatically makes all your data searchable.
The article will focus mainly on integrating full-text search capabilities into an e-commerce store using Nuxt, Tigris Search, and Netlify Functions. It skips over a few things like styling etc., which will be pre-generated in the template used for this tutorial.
Checkout the e-commerce full-text search demo for a working example of the e-commerce site that we'll build in this tutorial. The e-commerce full-text search demo source code is available on GitHub if you want to explore the code on your own. Otherwise, follow along with the tutorial.
Prerequisites
System Requirements
- Node.js 18.13.0 or newer
- MacOS, Windows, and Linux are supported
Tigris Cloud Account
To get started, go to the Tigris console and sign up.
Netlify CLI
This tutorial also requires the Netlify CLI to be installed.
Getting Started
The first step is to clone the repository that contains the starting source code.
git clone https://github.com/tigrisdata/tigris-netlify-ecommerce
cd into the project directory:
cd tigris-netlify-ecommerce
The layout of this project is like below:
tigris-netlify-ecommerce
├── package.json
└── pages
├── all.vue
├── cart.vue
├── index.vue
├── women.vue
└── men.vue
└── layouts

Create a Tigris Project
To obtain the necessary credentials to connect your e-commerce store application
with a Tigris database, you need to create a Tigris project. To do that, go to
your Tigris Cloud Console and click on the
Create a new project button. Then use catalog as the project name and click
on the Create button.
Select Go to Project in the next dialog.
Configure environment variables
Upon creation of a project, Tigris will automatically generate an application key with the required credentials for your application. Select Application Keys and click the eye icon on the row for the listed key. This will open a dialog containing the values you need to configure your local application with via environment variables:
| Dialog | Environment variable |
|---|---|
| URL | TIGRIS_URI |
| Client ID | TIGRIS_CLIENT_ID |
| Client Secret | TIGRIS_CLIENT_SECRET |
| Name | TIGRIS_PROJECT |
Now, create a .env file in the root directory of the project folder and copy
the values for TIGRIS_URI, TIGRIS_PROJECT, TIGRIS_CLIENT_ID, and
TIGRIS_CLIENT_SECRET from the dialog in the Tigris web console and add them to
the file. You should also include the TIGRIS_DB_BRANCH variable to establish a
branch for your Tigris database. It is a good practice to use the main branch
for a production environment and any other branch for development environments.
TIGRIS_URI=tigris_uri
TIGRIS_PROJECT=catalog
TIGRIS_CLIENT_ID=ftSxxx
TIGRIS_CLIENT_SECRET=DOxxx
TIGRIS_DB_BRANCH=main
Tigris Project and Application Key creation via the tigris-cli
tigris CLI Installation
For macOS: brew install tigrisdata/tigris/tigris-cli.
For other operating systems: See installation instructions here.
Create a Tigris Project
tigris create project ecommerce_search "search tutorial"
Create a Project Application Key
Once the project has been created, create an application key for the project:
tigris create app_key "my app key" --project=ecommerce_search --create-env-file
This will create a .env with your project configuration.
Add full-text search capabilities
To add full-text search to our application, we only need three things:
- Serverless functions to call Tigris search
- An async action in the vuex store to call Tigris search serverless function
- A search vue component for the search text in the UI
Step 1: Serverless functions to call Tigris Search
Let's write a serverless function to add search functionality to the e-commerce store. This serverless function will be used by the vuex store to power search functionality for the application.
⌲ Add the following code inside functions/search-products.ts.
import { Handler } from "@netlify/functions";
import tigrisDB from "../lib/tigris";
import { Product } from "../db/models/product";
const handler: Handler = async (event, context) => {
const searchReq = JSON.parse(event.body);
try {
const products = tigrisDB.getCollection<Product>(Product);
const searchResult = await products.search({ q: searchReq.q as string });
const productHits = new Array<Product>();
for await (const res of searchResult) {
res.hits.forEach((hit) => productHits.push(hit.document));
}
return {
statusCode: 200,
body: JSON.stringify(productHits),
};
} catch (err) {
console.log(err);
return {
statusCode: 500,
body: JSON.stringify({
status: err,
}),
};
}
};
export { handler };
The main thing to note in the above serverless function is that we are simply
calling search on the product collection.
Step 2: Integrate Search Serverless functions in vuex store
The next step is to integrate the serverless function that we have just added to
the vuex store. Here we will be adding an async action, searchProducts.
⌲ Add the following code inside actions export const actions = {...} in store/index.ts
async searchProducts({ commit }, keyword) {
try {
const response = await axios.post(
"/.netlify/functions/search-products",
{
q: keyword,
},
{
headers: {
"Content-Type": "application/json"
}
}
);
if (response.data) {
commit("searchProducts", response.data);
}
} catch (e) {
console.log("error", e);
}
}
The searchProducts async action is making a POST request with a parameter
q with a value assigned by the keyword variable. This request calls the
serverless function on the path /.netlify/functions/search-products. keyword
is the text the user wants to search for within the e-commerce catalog. We will
see in Step 3 how the vue is passing the text to this async action.
The next step is to update the mutations based on the actions that we have
added. Add the searchProducts in the export const mutations = {...} by
adding the following code.
searchProducts: (state, payload) => {
state.searchdata = payload;
};
Note: Add a new variable "searchdata" in the state so that mutations can update it.
Add a searchResult inside getters export const getters = {...} to access
search results
searchResult: (state) => state.searchdata;
Step 3: A search vue component for the search text in the UI
Create a search.vue file and add the following code to it:
<template>
<div>
<div class="searchHeader">
<input type="text" v-model="keyword" placeholder="Search Keyword" />
<button
class="searchBtn"
@click="search"
:disabled="loading || !keyword"
>{{(!loading) ? 'Search Products' : 'Loading...'}}</button>
</div>
<p class="noResults" v-if="usingSearch && !loading && searchResult.length<1">No results found..</p>
<app-store-grid :data="(usingSearch) ? searchResult : storedata" />
</div>
</template>
<script>
import AppStoreGrid from "~/components/AppStoreGrid.vue"
import { mapGetters, mapState } from 'vuex';
export default {
components: {
AppStoreGrid
},
computed: {
...mapGetters(["searchResult"]),
...mapState(["storedata"])
},
data() {
return {
keyword: "",
error: "",
loading: false,
usingSearch: false,
};
},
methods: {
search() {
this.loading = true;
this.usingSearch = true;
this.$store.dispatch("searchProducts", this.keyword).
then(() => {
this.loading = false;
})
}
}
};
</script>
<style lang="scss" scoped>
.noResults {
text-align: center;
}
.searchBtn {
width: 180px;
}
.searchHeader {
display: flex;
justify-content: center;
gap: 10px;
margin-bottom: 40px;
}
</style>
Add this search.vue to the AppNav.vue component.
<li>
<nuxt-link to="/search">Search</nuxt-link>
</li>
At this point, you have successfully integrated Search into your application. You can also check out the full-text search e-commerce example on GitHub.
Run the app
Let's reap the rewards. Run netlify dev using
netlify CLI in the terminal.
You should see the following output:
netlify dev
