Have you encountered Docker and CI/CD in the context of frontend development?

Yes, Docker is often used in frontend development to create isolated environments, for example, to run project builds or tests in a container with the required versions of Node.js and dependencies.

CI/CD (Continuous Integration/Continuous Deployment) helps automate the process of building, testing, and deploying frontend applications. For example, when code is pushed to a repository, a build, lint check, unit tests, and deployment to staging or production are automatically triggered.

An example of a simple Dockerfile for a React application:

FROM node:16-alpine
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
CMD ["npx", "serve", "-s", "build"]

In a CI/CD pipeline, steps for building and deploying can be configured using GitHub Actions, GitLab CI, or Jenkins.
