Building your Own SaaS

Creating a SaaS platform using Supabase, Nuxt, and Algolia is an exciting project that combines powerful technologies for a robust end product. Let’s walk through the steps to set this up:

Setting up a Nuxt Project

First, you need to set up a Nuxt project. Nuxt is a powerful Vue.js framework that simplifies web development. You can create a new Nuxt.js project using the create-nuxt-app.

npx create-nuxt-app my-project

Follow the prompts to set up your project. For this example, we are using Supabase for our backend, so you can skip choosing an Axios module or any backend framework.

Installing Necessary Packages

To integrate Supabase with your Nuxt project, you need to install the Supabase JavaScript client.

npm install @nuxtjs/supabase @nuxt/ui @nuxt/devtools @nuxt/ui-pro @nuxtjs/algolia

Integrating Supabase with Nuxt

Connecting Nuxt to Supabase

Now, you will need to initialize Supabase in your Nuxt project. This can be done using Nuxt Modules.

• Supabase Module

Example: Authentication in Nuxt with Supabase

Below is a basic example of how you might handle user authentication in your application.

login.vue

<script setup lang="ts">
const supabase = useSupabaseClient();
const user = useSupabaseUser();

const state = reactive({
	email: ''
});

const loginError = ref(false);
const loginSuccess = ref(false);

async function onSubmit() {
	const { error } = await supabase.auth.signInWithOtp({
		email: state.email,
		options: {
			emailRedirectTo: 'http://localhost:3000/confirm'
		}
	});

	if (error) {
		loginError.value = true;
		loginSuccess.value = false;
	} else {
		loginSuccess.value = true;
		loginError.value = false;
	}
}

watch(
	user,
	() => {
		if (user.value) {
			return navigateTo('/');
		}
	},
	{ immediate: true }
);
</script>

<template>
	<UContainer :ui="{ constrained: 'max-w-xl' }">
		<UCard class="mt-10">
			<template #header>
				<div class="flex justify-between">
					<h1 class="font-bold text-xl">Log in</h1>
					<UColorModeButton />
				</div>
			</template>

			<section>
				<UForm
					v-if="!loginError && !loginSuccess"
					:state="state"
					class="space-y-4"
					@submit="onSubmit"
				>
					<UFormGroup label="Email" name="email" v-slot="{ error }">
						<UInput
							v-model="state.email"
							type="email"
							placeholder="Enter email"
							:icon="error ? 'i-heroicons-exclamation-triangle-20-solid' : 'i-heroicons-envelope'"
						/>
					</UFormGroup>

					<UButton type="submit"> Submit </UButton>
				</UForm>
				<UAlert
					v-if="loginError"
					color="red"
					variant="subtle"
					icon="i-heroicons-exclamation-triangle-20-solid"
					title="There was an error"
					description="Please reload this page to try again."
				/>
				<UAlert
					v-if="loginSuccess"
					color="green"
					variant="subtle"
					icon="i-heroicons-check-badge"
					title="Check your email"
					description="A magic login link has been send to your email address."
				/>
			</section>
		</UCard>
	</UContainer>
</template>

Integrating Algolia with Nuxt

Connecting Nuxt to Aloglia

Now, you will need to initialize Algolia in your Nuxt project. This can be done using Nuxt Modules.

• Algolia Module

Example: Adding Search

This is a simple but very powerful feature to quickly add search into your frontend application.

algolia.vue

<script setup lang="ts">
import {
	AisInstantSearch,
	AisSearchBox,
	AisHits,
	AisRefinementList,
	AisConfigure
} from 'vue-instantsearch/vue3/es';

import { history } from 'instantsearch.js/es/lib/routers';
import { simple } from 'instantsearch.js/es/lib/stateMappings';

const routing = {
	router: history(),
	stateMapping: simple()
};

// import { translateLabel } from "../lib/helpers";

const indexName = 'codingcatdev-cats';
const algolia = useAlgoliaRef();

const links = [
	{
		label: 'Cat overview',
		icon: 'i-heroicons-list-bullet',
		to: '/cats'
	}
];

const columns = [
	{
		key: 'name',
		label: 'Name'
	},
	{
		key: 'color',
		label: 'Color'
	},
	{
		key: 'vacinated',
		label: 'vacinated'
	}
];

const selectedColumns = ref([...columns]);

function transformItems(items: any) {
	return items.map((item: any) => ({
		...item,
		label: item.label
	}));
}

function mapToTableRows(items: any) {
	return items.map((item: any) => {
		return {
			id: item.id,
			name: item.name,
			color: item.color,
			vacinated: item.vacinated,
			class: 'bg-gray-50 dark:bg-gray-950'
		};
	});
}
</script>

<template>
	<ais-instant-search :index-name="indexName" :search-client="algolia" :routing="routing">
		<ais-configure :hitsPerPage="100" />
		<UPage :ui="{ wrapper: 'max-w-full', left: 'pl-8' }">
			<template #left>
				<UAside>
					<h3 class="font-bold mb-2">Color</h3>
					<ais-refinement-list attribute="color" operator="and" :transform-items="transformItems">

						</div>

						<UTable :columns="selectedColumns" :rows="mapToTableRows(items)" />
					</template>
