Once we’ve created the function file, we have to make some necessary configurations in order for us to run our function locally. In the file, configure the purge option with the paths to all of the pages and components so Tailwind can tree-shake unused styles in production builds: //. Configure Tailwind to remove unused styles in production This will create a minimal file at the root of the project. Next, generate and files: npx tailwindcss init -p
#Npm install serverless g install#
Npm install -D the Tailwind configuration files Uninstall any previous Tailwind installation and re-install the compatibility build: npm uninstall tailwindcss postcss autoprefixer To install Tailwind, we’ll use the PostCSS 7 compatibility build, since Tailwind depends on PostCSS 8 - which at the time of writing is not yet supported by Vue 3. Run cd link-previewer to enter the newly created project. Select Y (yes) or N (no) and continue with the installation. ? Where do you prefer placing config for Babel, ESLint, etc.? In dedicated config filesĪfter selecting these options, we’ll be asked if we want to save the options as a preset for later use.
? Pick additional lint features: Lint on save ? Pick a linter / formatter config: Basic ? Use history mode for router? (Requires proper server setup for index fallback in production ) Yes ? Choose a version of Vue.js that you want to start the project with: 3.x ? Check the features needed for your project: Choose Vue version, Babel, PWA, Router, Vuex, Linter Here are the options I selected: Please pick a preset: Manually select features We’ll select “Manually select features” so that we can pick the features we need.
This will prompt us to pick a preset for our installation. To install Vue CLI, run: npm install -g the CLI has been installed, we can create a project by running: vue create link-previewer To quickly scaffold a Vue application, we’ll use Vue CLI. We’ll also install and set up Tailwind CSS, a utility-first CSS framework that provides classes we can use for our app without having to write a lot of custom CSS. We’re going to create a Vue 3 application using Vue CLI. And here’s the GitHub Repo to follow along. Here’s the link to the example project deployed on Netlify. The function sends the metadata and screenshots back to the component on our front-end to display it as a link preview in the application. The function then uses Puppeteer to get metadata from the target site using the URL and to generate a screenshot of the site. This component sends a request with a URL to our serverless function.
To show how we can easily set up serverless functions with our front-end application, we’ll be building an app with a custom link previewer component. You can create one if you haven’t already. You should also have an account on Netlify.
You can check your version of Node by running the command node -vin your terminal. You should also have a text editor - such as VS Code) with Vetur installed (for IntelliSense) - and a recent version of Node installed on your machine. To follow along with this tutorial, you’ll need to be familiar with JavaScript, Vue.js, Git, GitHub, and Netlify. Netlify functions make creating and deploying serverless functions easy for applications hosted on Netlify. The functions are hosted and deployed by cloud computing companies. With serverless functions, developers can create and implement modern features and functionalities in their applications without going through the pain of setting up and managing back-end servers. In s-project.In this tutorial, we’re going to see how we can deploy serverless functions alongside our front-end application and create an API that generates images and grabs metadata from links. You can create a dependency-a by executing sls dependency create -n dependency-a |_package.json // Optional if you have other npm dependencies Create directories for each of the dependencies with a index.js inside, as shown below. What if you need to share code, but don't wish to publish packages in NPM Registry? You can use the local shared dependencies.Ĭreate a directory(e.g 'local_shared_dependencies') in your serverless root to store shared local dependency(library) code.
#Npm install serverless g code#
This creates the template code for local shared dependency, inside the directory with the name shared, in project root. Then in s-project.json add following entry to the plugins array: serverless-dependency-installĮ.g "plugins": Using the Plugin Npm install -save serverless-dependency-install This plugin also allows to define local shared dependencies in package.json.Executes npm install for all the package.json files inside serverless project directory with a single command.
