Deploy
Build
Creating a state optimized for deployment by removing unnecessary data and integrating/compressing data spread across multiple branches
Compared to before the build process, there are advantages of reduced data capacity and faster website loading speed
Build in the general sense means the compilation process of converting source code into executable bundles
It's slightly different for web apps deployed in HTML, CSS, JS format, and web apps must be made into static files that can be deployed
Deployment
A series of processes to make developed services available to users
In deployment, it's important to understand environmental differences and separate environment configuration from code
4 Stages of Deployment
Development
Process of writing and testing code on each person's computer
Since it's the development stage, testing is done with dummy data instead of real data
Integration
Process of combining code written on each person's computer
Checking whether my written code doesn't interfere with other code causing errors, and checking for conflicts between codes
Staging
Testing in an environment most similar to the Production stage, which is the actual release stage
Testing in various environments by copying real data to check for problems
May also go through verification processes by relevant departments or personnel
Production
Stage of releasing the developed service
Running code in the Production environment where users can access and providing the service
Since the service operates with real data, this is a stage where problems should not occur
How to Make Written Code Work Properly in Different Environments?
Use relative paths instead of absolute paths
Set environment variables (env) to branch ports according to environment
Environment variables can be easily changed for each deployment without code changes
Unlike configuration files, there's also a lower possibility of accidentally uploading to the code repository
Use solutions like Docker to unify the development environment itself
