Front end scaffold

Vercel

This is a project template which could be used to the creation of new projects. Some of the features included are:

This scaffold is only an example of how to develop an application following some of the standards we set in the Front-end team. Please adapt your project needs to this scaffold, or use it as a reference.

WE STRONGLY RECOMMEND most of the cases use this scaffold as a reference and not as a starting point. This scaffold is a good starting point for projects that will be developed by a single person, or when the project is a small one. For bigger projects, we recommend to create a new project from scratch and follow the standards and guidelines we have in the Front-end team. To facilitate this process, we recommend follow this CLI from NextJs.

npx create-next-app@latest

Note: we are preparing an alternative documentation still in progress. We'll communicate the progress in the Front-end channels.

Repository Documentation

Run the application and go to http://localhost:3000/docs to see the application documentation.

The components documentation files are stored on the docs-containers folder. This containers may be deleted when doing a clean up of the project.

Getting Started

Installing dependencies

By default, the scaffold comes with Yarn as package manager, so now we can install the dependencies by running:

yarn install

Note: these instructions assume the project uses Node >= 18, for other scenarios check Yarn documentation

Quick start

First, run the development server:

yarn dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying pages/index.tsx. The page auto-updates as you edit the file.

API routes can be accessed on http://localhost:3000/api/hello. This endpoint can be edited in pages/api/hello.js.

The pages/api directory is mapped to /api/*. Files in this directory are treated as API routes instead of React pages.

Deploy on Vercel

First, we recommend to read the guideline about how to use Vercel.

The easiest way to deploy your Next.js app is to use the Vercel Platform from the creators of Next.js.

Check out the Next.js deployment documentation for more details.

Contribution rules

Please, create a PR for any improvement or feature you want to add. Try to not commit directly anything on the main branch.

Vulnerability mitigation

Dependabot's vulnerability security alerts are configured in this repository and are displayed to the administrators.

When vulnerabilities are detected, a warning message is displayed at the top of the repository. The list of alerts can be found in the Dependabot alerts page.

Here's a step by step guide on how to address vulnerabilities found in production code:

  1. Go to the Dependabot alerts page and locate the front-end vulnerability to address
  2. Identify if the vulnerability affects production code:
    • To do so run yarn npm audit --recursive --environment production
    • If the dependency is not listed by this command, then the vulnerability only affects development code. You can dismiss the alert on GitHub as “Vulnerable code is not actually used” in the top right corner of the vulnerability page.
    • If the dependency is listed, follow the steps below.
  3. On the vulnerability page, click the “Create Dependabot security update” button
    • This will create a Pull Request with a fix for the vulnerability. If GitHub can generate this PR, then you can merge and the security alert will disappear.
    • If the vulnerability can't be patched automatically, follow the steps below.
  4. If the action fails, then you can semi-automatically update the vulnerable dependency by running npm_config_yes=true npx yarn-audit-fix --only prod
    • yarn-audit-fix (see repository) is a tool that applies the fixes from npm audit fix to Yarn installations
    • The tool might also not be able to fix the vulnerability. If so, continue with the steps below.
  5. If the action fails, then you will have to manually update the dependencies until the vulnerability is solved

Env variables

Variable nameDescriptionDefault value
NEXTAUTH_SECRETKey used to encrypt the NextAuth.js JWT, and to hash email verification tokens. Do not forget to add a secret. NextAuth can handle without it in development mode, but it won't in production! https://next-auth.js.org/configuration/options#secret
NEXTAUTH_URLNeeded by the next-auth library for handling auth requests and callbacks. Set the environment variable to the canonical URL of your site. Not needed in Vercel deploys.
NEXT_PUBLIC_API_URLURL of the API.http://localhost:3000
STORYBOOK_API_URLURL of the API for storybook.
NEXT_PUBLIC_MAPBOX_API_TOKENMapbox token.
NEXT_PUBLIC_GA_TRACKING_IDGoogle Analytics tracking ID. If you're working with an Google Analytics 4 property, you have a Measurement ID instead of a Tracking ID.
