Comprehensive Model Answer
Verified Solution
You can define custom language blocks inside *.vue files based on the lang attribute of the block, the block's
tag name, and the rules in your webpack config. You can also use resourceQuery to match a rule against a custom
block with no lang.
For example, to match against <message> custom blocks.
{
module: {
rules: [
{
resourceQuery: /blockType=message/,
loader: 'loader-to-use'
}
]
}
}

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.
