Questions tagged [continuous-integration]

Continuous integration (CI) is the building and automated testing of the full software product on a frequent schedule: at least once a day, often several times a day and sometimes as often as after every check in to the version control system.

Concept

Continuous integration is an important part of an agile software development process. Integration is an important step to detect quality issues, so if it is done frequently, problems will be detected earlier and fewer at a time. Hence, continuous integration can help to reduce the overall cost of the process. Although continuous integration could be automated with simple scripting, it is generally more advantageous to use tools built for this purpose, especially for complex projects with many modular parts.

Tools

One of the first tools to become popular for this purpose was CruiseControl. Now there are many such products, both open source and proprietary.

References

Martin Fowler has a good writeup of what it all means in Continuous Integration.

What is the difference between "npm install" and "npm ci"?

I'm working with continuous integration and discovered the npm ci command. I can't figure what the advantages are of using this command for my workflow. Is it faster? Does it make the test harder, okay, and after?
