How to Develop a CRUD Application with Nuxt.js?

overview in this walkthrough, you'll discover how to build a fully operational crud (create, read, update, delete) application using nuxt js we’ll use back4app as our backend service to handle data storage and management with ease this guide covers essential crud functions, detailing how to set up a back4app project, create a versatile data model, and integrate crud operations with your nuxt js application initially, you will configure a back4app project named basic crud app nuxt which offers a powerful nosql data storage environment you will define your data structures by establishing classes and fields either manually or through back4app’s intelligent ai agent next, you will manage your backend using the back4app admin app—a user friendly, drag and drop interface for efficient data operations finally, you will connect your nuxt js application to back4app using rest api calls to perform secure crud operations by the end of this guide, you will have created a production ready nuxt js application capable of handling basic crud operations along with secure user authentication and data management main points learn how to build a nuxt js crud application with a high performance backend understand the process of designing a scalable backend and linking it to your nuxt js frontend explore how back4app’s admin app simplifies data operations like create, read, update, and delete get insights into deployment methods including docker containerization for a seamless production rollout prerequisites before you begin, ensure that you have a back4app account with a newly configured project if you need help, refer to getting started with back4app https //www back4app com/docs/get started/new parse app a development environment for nuxt js ensure you have node js installed and set up an ide or text editor of your choice basic knowledge of nuxt js, vue js, and rest apis consult the nuxt js documentation https //nuxtjs org/docs if you need a refresher step 1 – project initialization setting up a new back4app project log in to your back4app account select the “new app” option from your dashboard name your project basic crud app nuxt and follow the setup instructions create new project after the project is created, it will appear on your dashboard, ready for further backend configuration step 2 – crafting the data model establishing your data structures for this crud application, you will set up several classes (or collections) within your back4app project below are examples of key classes and their fields needed for basic crud functionality 1\ items collection this collection stores details about each item field type description id objectid system generated unique identifier title string name of the item description string brief description of the item createdat date timestamp marking item creation updatedat date timestamp marking last update 2\ users collection this collection manages user details and authentication information field type description id objectid auto generated unique identifier username string unique username for the user email string user's unique email address passwordhash string hashed password for secure authentication createdat date account creation timestamp updatedat date timestamp for account modifications you can define these collections and fields manually in the back4app dashboard create new class you add fields by choosing the appropriate data type, naming the field, optionally setting a default value, and specifying if the field is mandatory create column utilizing the back4app ai agent for schema generation the back4app ai agent is a handy tool within your dashboard that can automatically build your schema from a provided description this feature accelerates the setup process and ensures your data model is optimized for crud operations how to use the ai agent open the ai agent access it from your project settings in the back4app dashboard describe your schema provide a detailed prompt outlining the classes and fields you need review and confirm the ai agent will generate a schema proposal review it and confirm to apply the changes example prompt create the following collections in my back4app project 1\) collection items \ fields \ id objectid (auto generated) \ title string \ description string \ createdat date (auto generated) \ updatedat date (auto updated) 2\) collection users \ fields \ id objectid (auto generated) \ username string (unique) \ email string (unique) \ passwordhash string \ createdat date (auto generated) \ updatedat date (auto updated) this smart feature saves time and ensures your data structure is consistently set up for optimal crud operations step 3 – enabling the admin app & handling crud operations overview of the admin app the back4app admin app provides a no code interface for seamless backend data management its drag and drop features make it easy to perform crud operations like adding, editing, viewing, and deleting records activating the admin app go to the “more” menu in your back4app dashboard choose “admin app” and click on “enable admin app ” set up your admin account by creating initial credentials this step will also create system roles such as b4aadminuser and configure essential system collections enable admin app once enabled, log in to the admin app to manage your application’s data effortlessly admin app dashboard using the admin app for crud operations inside the admin app, you can add new entries utilize the “add record” button in a collection (like items) to insert data view and edit click on any record to inspect its details or make modifications delete entries remove records that are no longer required this intuitive interface streamlines data management for your application step 4 – connecting your nuxt js application to back4app with your backend in place, the next task is to integrate your nuxt js app with back4app using rest api calls since the parse sdk is not commonly used with nuxt js, you will perform crud operations using rest api calls setting up api requests in nuxt js install axios if not already installed, add axios to your nuxt js project npm install @nuxtjs/axios configure axios module in your nuxt config js , include the axios module and set up basic configuration export default { modules \['@nuxtjs/axios'], axios { baseurl 'https //parseapi back4app com' } } performing crud operations create a service (for example, services/items js ) to handle api calls below is an example of how you might fetch, create, update, and delete items // services/items js export default { async fetchitems() { try { const response = await this $axios $get('/classes/items', { headers { 'x parse application id' 'your application id', 'x parse rest api key' 'your rest api key' } }); return response results; } catch (error) { console error('error fetching items ', error); return \[]; } }, async additem(title, description) { try { const response = await this $axios $post('/classes/items', { title, description }, { headers { 'x parse application id' 'your application id', 'x parse rest api key' 'your rest api key' } }); return response; } catch (error) { console error('error creating item ', error); } }, async updateitem(objectid, newtitle, newdescription) { try { const response = await this $axios $put(`/classes/items/${objectid}`, { title newtitle, description newdescription }, { headers { 'x parse application id' 'your application id', 'x parse rest api key' 'your rest api key' } }); return response; } catch (error) { console error('error updating item ', error); } }, async removeitem(objectid) { try { const response = await this $axios $delete(`/classes/items/${objectid}`, { headers { 'x parse application id' 'your application id', 'x parse rest api key' 'your rest api key' } }); return response; } catch (error) { console error('error deleting item ', error); } } } integrate these api methods within your nuxt js pages or components to enable full crud functionality step 5 – enhancing security implementing access control lists (acls) secure your data by setting up acls for individual objects for instance, you can restrict an item so that only its creator can view or modify it async function createprivateitem(title, description, userid) { try { const acl = { " " { "read" false, "write" false }, \[userid] { "read" true, "write" true } }; const response = await this $axios $post('/classes/items', { title, description, acl acl }, { headers { 'x parse application id' 'your application id', 'x parse rest api key' 'your rest api key' } }); console log('private item created ', response); } catch (error) { console error('error creating private item ', error); } } setting class level permissions (clps) in your back4app dashboard, configure clps to enforce default access policies, ensuring that only authenticated users can interact with specific collections step 6 – implementing user authentication setting up user registration and login back4app leverages a built in users collection for managing authentication in your nuxt js app, implement registration and login using rest api calls example user registration and login export default { async registeruser(username, password, email) { try { const response = await this $axios $post('/users', { username, password, email }, { headers { 'x parse application id' 'your application id', 'x parse rest api key' 'your rest api key' } }); console log('user registered ', response); return response; } catch (error) { console error('registration error ', error); } }, async loginuser(username, password) { try { const response = await this $axios $get('/login', { params { username, password }, headers { 'x parse application id' 'your application id', 'x parse rest api key' 'your rest api key' } }); console log('user logged in ', response); return response; } catch (error) { console error('login error ', error); } } } this approach supports session management, password recovery, and additional authentication features step 7 – deploying your nuxt js application back4app simplifies the deployment process you can deploy your nuxt js app using various methods, including docker containerization 7 1 building your nuxt js project build the application run the following command to generate the production build npm run build start the application test your production build locally using npm run start 7 2 organizing your project structure a typical nuxt js project structure may look like basic crud app nuxt/ \| assets/ \| components/ \| layouts/ \| pages/ \| plugins/ \| services/ \| | items js \| | auth js \| static/ \| nuxt config js \| package json \| dockerfile 7 3 dockerizing your nuxt js app if you prefer containerization, include a dockerfile at your project’s root \# use a node js image as the base from node 16 alpine \# set working directory workdir /app \# copy package files and install dependencies copy package json / run npm install \# copy the rest of the application copy \# build the application run npm run build \# expose the port (adjust if necessary) expose 3000 \# start the application cmd \["npm", "run", "start"] 7 4 deploying via back4app web deployment connect your repository ensure your nuxt js project is hosted on github configure deployment in your back4app dashboard, navigate to the web deployment section, link your repository (e g , basic crud app nuxt ), and select the appropriate branch set build instructions define the build command (such as npm run build ) and specify the output directory deploy click deploy and follow the logs until your application is live step 8 – wrapping up and future steps great job! you’ve now built a nuxt js crud application integrated with back4app you created a project named basic crud app nuxt , designed collections for items and users, and managed your data through the back4app admin app additionally, you connected your nuxt js app via rest api calls and implemented strong security measures what’s next feature expansion consider adding functionalities like advanced search filters, detailed item views, or real time updates backend enhancements look into cloud functions, integrations with external apis, or role based permissions further learning explore the back4app documentation
