It works on an incremental principle: *minimal rebuilding for a minimal change*. --- ### Key characteristics of an incremental bundler 1. **The initial build is full**, with the module graph being constructed. 2. **Subsequent builds are partial**, touching only the changed files and the graph nodes related to them. 3. **Aggressive caching** - the results of previous builds are stored and reused. 4. **Fast HMR** - only the specific module is updated, not the whole chain. --- ### Why this is needed | Problem with regular bundlers | What an incremental bundler solves | |---|---| | rebuilding grows with project size | speed does not drop as the codebase grows | | slow HMR | instant module updates | | CPU cost on every rebuild | minimal work per update | --- ### Summary The term **incremental bundler** denotes a bundler that uses *incremental rebuilding and caching* to keep development speed and HMR high regardless of the project's scale.For the reviewerNote to the moderator (optional)Visible only to the moderator.
