Known weaknesses
Each one links to the public issue, changelog or docs page it came from, where we have one.
- 01
Steep learning curve for new users
The documentation assumes familiarity with advanced concepts like plugins and middleware, which can be overwhelming for beginners.
- 02
Limited community support and small user base
Compared to more established tools like Webpack or Rollup, FuseBox has fewer contributors and a smaller number of active users on forums and Q&A sites.
- 03
Frequent breaking changes between versions
Historical version updates have introduced significant API changes, requiring substantial refactoring in existing projects to maintain compatibility.
- 04
Complex setup and configuration
Setting up a project with FuseBox involves configuring multiple plugins and middleware components, which can be time-consuming and error-prone for new users.
