Comprehensive Model Answer
Verified Solution
A Vue CLI preset is a JSON object that contains pre-defined options and plugins for creating a new project without
interactive prompts to select them. During project creation(using vue create), the presets will be saved in a~/.vuerc which can modified at any time.
For example, the generated JSON object(or preset) would be as below
{
"useConfigFiles": true,
"router": true,
"vuex": true,
"cssPreprocessor": "sass",
"plugins": {
"@vue/cli-plugin-babel": {},
"@vue/cli-plugin-eslint": {
"config": "airbnb",
"lintOn": ["save", "commit"]
}
}
}

Candidate Response Strategy & Interview Tips
- Start with a concise one-sentence summary: Deliver a direct, confident answer first before expanding into nuances.
- Demonstrate real-world trade-offs: Discuss where this approach excels and when you would avoid it in production systems.
- Discuss complexity & edge cases: Proactively explain time/space complexity or boundary conditions (null values, scale limits).
- Prepare for interviewer follow-ups: Technical hiring panels frequently probe deeper into concurrency, backward compatibility, or alternative libraries.
