Step 1 - Create Our Frontend Using Nuxtjs

Clone the repo of this open source marketplace frontend here :

gakpenting / opensource-marketplace-frontend

DEPLOY TO DO BUTTON

Build Setup

# install dependencies
$ yarn install

# serve with hot reload at localhost:3000
$ yarn dev

# build for production and launch server
$ yarn build
$ yarn start

# generate static project
$ yarn generate

For detailed explanation on how things work, check out Nuxt.js docs.

View on GitHub

First of all create a nuxtjs application by using this command :

yarn create nuxt-app opensource-marketplace-frontend

Create your application using this settings :

? Project name: frontend
? Programming language: TypeScript
? Package manager: Yarn
? UI framework: Vuetify.js
? Nuxt.js modules: Axios
? Linting tools: ESLint, Prettier
? Testing framework: Jest
? Rendering mode: Universal (SSR / SSG)
? Deployment target: Static (Static/JAMStack hosting)
? Development tools: (Press <space> to select, <a> to toggle all, <i> to invert selection)
? Continuous integration: None
? Version control system: None

After finish run the app using yarn dev and you should see this screen :

Now go to the nuxt.config.js and search for this line below, and change dark to false :

...
vuetify: {
    defaultAssets: {icons: 'fa'},
    customVariables: ['~/assets/variables.scss'],
    theme: {
      dark: false,
      themes: {
        dark: {
...

We will be using non dark mode for now but it's a matter of choice if you want to make it dark you can just put it to true, now after you change the theme to light then change the content in layouts/default.vue :

<template>
  <v-app >
<nuxt/>
  </v-app>
</template>

After you finish filling the content inside layouts/default.vue, go to pages/index.vue and write this code, to create our homepage :

<template>
  <Home :login="login" />
</template>
<script lang="ts">
import Cookies from 'js-cookie'
import Home from '@/components/Home.vue'
import { Component, Vue } from 'nuxt-property-decorator'
@Component({
  components: {
    Home,
  },
})
export default class MyStore extends Vue {
  public login: boolean =false;

      mounted(){
        this.login=Cookies.get('token') && Cookies?.get('token')?.trim() !== ''
      ? true
      : false
      }
}
</script>

Here you can see that index.vue use Home as their base component, let's now create our Home component, create components/Home.vue then write code like this :

<template>
  <div :class="['mx-5', 'my-5']">
    <v-row justify="center">
      <div
        :class="[`text-h1`, 'text-center']"
        v-text="'Open Source Marketplace'"
      ></div>
    </v-row>
    <v-row justify="center">
      <div
        :class="[`text-h3`, 'px-5', 'text-center', 'my-5']"
        v-text="'Here you can buy or sell open source repo'"
      ></div>
    </v-row>
    <v-row justify="center" :class="['my-2']">
      <v-btn
        :class="['my-2']"
        color="info"
        elevation="2"
        v-show="login"
        href="/dashboard"
        >DASHBOARD</v-btn
      >
      <v-btn
        :class="['my-2']"
        color="info"
        elevation="2"
        href="/login"
        v-show="!login"
        >LOGIN</v-btn
      >
      <v-btn
        :class="['my-2', 'mx-2']"
        color="error"
        elevation="2"
        v-show="login"
        @click="logout"
        >LOGOUT</v-btn
      >
    </v-row>
    <v-row>
      <v-card
        class="mx-auto my-12"
        max-width="374"
        :key="index"
        v-for="(item, index) in forSale"
      >
        <v-img height="250" :src="item.openGraphImageUrl"></v-img>

        <v-card-title>{{ item.name }}</v-card-title>

        <v-card-text>
          <div>{{ item.description }}</div>
        </v-card-text>

        <v-divider class="mx-4"></v-divider>

        <v-card-actions>
          <v-flex>$ {{ item.amount }}</v-flex>
          <v-flex v-if="item.username !== username && !item.owned"
            ><div class="d-flex justify-end">
              <v-btn
              :disabled="disabled"
                class="d-flex justify-end"
                color="deep-purple lighten-2"
                @click="buyNow(item._id)"
                text
              >
                Buy Now
              </v-btn>
            </div></v-flex
          >
          <v-flex v-if="item.username === username || item.owned"
            ><div class="d-flex justify-end">

              <v-btn

  </div>
</template>
<script lang="ts">
import Cookies from 'js-cookie'

And then you will got this as a homepage :

Go to nuxt.config.js and add server object

import colors from 'vuetify/es5/util/colors'

export default {
  // Target (https://go.nuxtjs.dev/config-target)
  server: {
    port: 8080, // default: 3000

          success: colors.green.accent3,
        },
      },
    },
  },

  // Build Configuration (https://go.nuxtjs.dev/config-build)
  build: {},
}

Create a login page go to pages/login.vue to create a login form that can login to github

<template>
  <Login />
</template>
<script lang="ts">
import Login from '@/components/Login.vue'
import { Component, Vue } from 'nuxt-property-decorator'
@Component({
  components: {
    Login,
  },
})
export default class MyStore extends Vue {}
</script>

Create the component in components/Login.vue

<template>

   <v-row justify="center" align="center">
<v-card>
  <v-card-text>
    <v-row :class="['my-3','mx-3','text-h4']">LOGIN USING YOUR GITHUB ACCOUNT</v-row>
    <v-row align="center" justify="center">
      <v-btn @click="login_github"><v-icon class="mx-2 my-2">fab fa-github</v-icon>LOGIN</v-btn>
    </v-row>
  </v-card-text>
</v-card>
   </v-row>

</template>
<script lang="ts">
import { Component, Vue } from 'nuxt-property-decorator'
import {configs} from '@/utils/configs.js'
@Component
export default class MyStore extends Vue {
  login_github(){
    window.location.href="https://github.com/login/oauth/authorize?scope=repo&client_id="+configs.github_client_id
  }
}
</script>

Notice that we added configs.github_client_id you can get that by creating oauth apps in github developer setting https://github.com/settings/developers create new oauth apps then copy paste the github client id there,now let's create our environment variable create a folder called utils and then create a file called configs.js this will be our global configuration to get variable like github_client_id, github_client_secret etc.

const configs={}
configs.url=process.env.url;
configs.prefix=process.env.prefix;
configs.github_client_id=process.env.github_client_id
configs.paypal_client_id=process.env.paypal_client_id
configs.save_paypal_url=`${configs.url}${configs.prefix}/save-paypal`
configs.buy_paypal_url=`${configs.url}${configs.prefix}/buy-paypal`
configs.for_sale_repo_url=`${configs.url}${configs.prefix}/for-sale-repo`
configs.disconnect_paypal_url=`${configs.url}${configs.prefix}/disconnect-paypal`
configs.redirect_uri_paypal=`${configs.url}${configs.prefix}/paypal-auth`
configs.unlist_repo_url=`${configs.url}${configs.prefix}/unlist-repo`
configs.sell_repo_url=`${configs.url}${configs.prefix}/sell-repo`
configs.get_all_repo_url=`${configs.url}${configs.prefix}/get-all-repo`
configs.get_profile_url=`${configs.url}${configs.prefix}/get-profile`
configs.get_for_sale_url=`${configs.url}${configs.prefix}/get-for-sale-repo`
configs.get_owned_repo_url=`${configs.url}${configs.prefix}/get-owned-repo`
configs.get_paypal_url=`${configs.url}${configs.prefix}/get-paypal`
configs.list_repo_url=`${configs.url}${configs.prefix}/list-repo`
configs.repo_detail_url=`${configs.url}${configs.prefix}/repo-detail`
module.exports={configs}

When in development you also need .env file to make it easy to handle the environment variable go ahead and create .env with this value :

github_client_id=<github_client_id>
paypal_client_id=<paypal_client_id>
url=http://localhost:4000
prefix=

Change the value according to your need,after that create a dashboard go to pages/dashboard.vue and write this code :

<template>
  <Dashboard :login="login" />
</template>
<script lang="ts">
import Cookies from 'js-cookie'
import Dashboard from '@/components/Dashboard.vue'
import { Component, Vue } from 'nuxt-property-decorator'
@Component({
  components: {
    Dashboard,
  },
})
export default class MyStore extends Vue {
  public login: boolean =false;

      mounted(){
this.login=Cookies.get('token') && Cookies?.get('token')?.trim() !== ''
      ? true
      : false
      }
}
</script>

Create a dashboard component to make it more easy to maintain late go ahead and create components/Dashboard.vue and write this code :

<template>
  <v-container>
    <v-row justify="space-between">
      <v-col cols="4" class="text-h4 font-weight-bold"
        ><a href="/" style="text-decoration: none; color: black">Home</a></v-col
      >
      <v-col cols="4" class="d-flex justify-end"
        ><v-btn @click="logout">LOGOUT</v-btn></v-col
      >
    </v-row>
    <DashboardInfo
      :disabled="disabled"
      :username="username"
      :profilePhoto="profilePhoto"
      :paypalToken="paypalToken"
      :paypalBalance="paypalBalance"
      @disconnect="disconnectPaypal"
      @connect="connectPaypal"
    />
    <v-row justify="space-between">
      <v-col cols="4" class="text-h4 font-weight-bold"
        >For Sale Repo List</v-col
      >
    </v-row>
    <DashboardForSale
      :disabled="disabled"
      :ownedRepo="false"
      :amountRefresh="amountRefresh"
      @get-all-repo="getAllRepo"
      :listRepo="forSale"
      :paypalToken="paypalToken"
      @sell-repo="sellRepo($event.name, $event.amount)"
      @unlist-repo="unlistRepo($event.repo_id)"
    />
    <v-row justify="space-between">
      <v-col cols="4" class="text-h4 font-weight-bold">Owned Repo</v-col>
    </v-row>
    <DashboardOwned
      :amountRefresh="amountRefresh"
      :disabled="disabled"
      :ownedRepo="true"
      :paypalToken="paypalToken"

Inside Dashboard.vue component if you notice there is four more component inside the Dashboard.vue component we make that so that the component is more modular and easy to maintain for later use, now let's go ahead and create the first Dashboard.vue modular component components/dashboard_components/DashboardInfo.vue we will use this to get an info of our paypal balance and github username :

<template>
  <v-row>
    <v-card max-width="344" outlined>
      <v-list-item three-line>
        <v-list-item-content>
          <v-list-item-title class="headline mb-1">

<script lang="ts">
import { Component, Vue, Prop,Emit } from 'nuxt-property-decorator'

After that go ahead and create our second modular component components/dashboard_components/DashboardForSale.vue we will use this component to show our repo that we can sell :

<template>
  <div>
    <v-row class="mb-2" ><v-btn @click="getAllRepo" :disabled="disabled">SELL REPO</v-btn></v-row
    >

      >
        <v-card-title>
          <v-list-item class="grow">

              <v-list-item-title>{{ item.name }}</v-list-item-title>

            <v-row align="center" justify="end"> {{item.isPrivate?"Private":"Public"}} </v-row>
          </v-list-item>

      </v-card>

  </div>
</template>
<script lang="ts">

After that add components/dashboard_component/DashboardOwned.vue to see all of our that we bought from opensource marketplace

Finally add components/dashboard_components/DashboardRepoAll.vue to show all our repo from our github :

<template>
<v-row justify="center">
      <v-dialog
        v-model="dialog"
                max-width="600px"

          </v-card-title>
          <v-card-text>
          <v-card
    class="mx-auto"
    max-width="344"
    outlined
    :key="index"
v-for="(item, index) in allRepo"
  >
    <v-list-item three-line>
      <v-list-item-content>
        <div class="overline mb-4">
          {{item.isPrivate?"PRIVATE":"PUBLIC"}}
        </div>
        <v-list-item-title class="headline mb-1">
          {{item.name}}
        </v-list-item-title>
        <v-list-item-subtitle>{{item.description}}</v-list-item-subtitle>
      </v-list-item-content>

      <v-list-item-avatar
        tile

        color="grey"
      ><v-img :src="item.openGraphImageUrl"/></v-list-item-avatar>
    </v-list-item>

    <v-card-actions>
      <v-btn
        v-if="!item.added"
        rounded

        color="blue"
        :disabled="disabled"
        @click="listRepo(item)"
      >
        LIST REPO
      </v-btn>

    </v-card-actions>
  </v-card>
            <v-row justify="center" class="mt-2">
               <v-btn
      class="mx-2"
      fab
      dark
      large
      color="cyan"
      :disabled="!pageInfo_.hasPreviousPage||disabled"
      @click="getAllRepo(undefined,pageInfo_.startCursor)"
    >
      <v-icon>
        fas fa-arrow-left
      </v-icon>
    </v-btn>
                <v-btn

      fab

      :disabled="!pageInfo_.hasNextPage||disabled"
      @click="getAllRepo(pageInfo_.endCursor,undefined)"
    >
      <v-icon>

    </v-btn>
            </v-row>

          </v-card-text>

        </v-card>
      </v-dialog>
    </v-row>
</template>
<script lang="ts">
import { Component, Vue, Prop, Emit } from 'nuxt-property-decorator'

  }
  @Emit()
  listRepo(item:object) {
    return { item}
  }

}
</script>

Now in order for us to accept the redirect url we need route to save the token that we get from github login create pages/callback.vue in order to do that and write this code :

<template>
  <v-row justify="center" align="center" :class="['text-h1']"
    >REDIRECTING...</v-row
  >
</template>
<script lang="ts">
import Cookies from 'js-cookie'
import { Component, Vue } from 'nuxt-property-decorator'
import axios from 'axios'
import {configs} from '@/utils/configs.js'
@Component
export default class MyStore extends Vue {
  async mounted() {
    if (this.$route.query.token) {
      Cookies.set('token', this.$route.query.token)
      if(Cookies.get('redirect')){
        const redirect=Cookies.get('redirect');
        window.location.href=`${redirect}`;
        return
      }
      window.location.href = '/'
    } else {
      const token = Cookies.get('token')
      const { data } = await axios.post(`${configs.save_paypal_url}`, {
        token,
        email: this.$route.query.email,
      })
      if (data.status) {
        window.location.href = '/dashboard'
      } else {
        window.location.href = '/dashboard?error=save_paypal'
      }
    }
  }
}
</script>

We also need to have a link where we can share the repo that we sell go create one at pages/detail

<template>
  <v-row justify="center" align="center" :class="['text-h1']"
    >
  <v-card

    class="mx-auto my-12"
    max-width="1000"

    <template slot="progress">

        height="10"
        indeterminate

    </template>

    <v-img
      height="250"
      :src="item.openGraphImageUrl"
    ></v-img>

    <v-card-title>{{item.name}}</v-card-title>

    <v-card-text>



      <div>{{item.description}}</div>
    </v-card-text>

    <v-divider class="mx-4"></v-divider>

    <v-card-title>$ {{item.amount}}</v-card-title>



    <v-card-actions>
      <v-btn
         v-if="item.username !== username_"
        color="deep-purple lighten-2"
        text
        :disabled="disabled"
        @click="buyNow(item.repo_id,item.username,item.name)"

                text
              >
                GO TO URL
              </v-btn>
    </v-card-actions>
  </v-card>
</v-row>
</template>
<script lang="ts">

      const {data}=await axios.post(`${url}`,{username,name})
this.item=data


  if(Cookies.get("token")){
        const token=Cookies.get("token")
        const _url = configs.get_profile_url

Now you finish creating the frontend let's go create the backend on step 2
