Rapid Development
Build and deploy a working app in just 15 minutes
You’ll need a Replit account and Core subscription to access Agent.
Start with Agent
Understand the library
We’ll use MarkItDown, Microsoft’s file conversion library. Since it’s new, provide Agent with context about its capabilities:
Create your prompt
Craft a clear prompt explaining your vision:
Hover over library URLs and select “copy content” to give Agent additional context.
Review the plan
Agent will create a development plan outlining:
- Required files
- Code structure
- Implementation steps
Develop iteratively
Using Agent for major changes
Agent excels at handling structural changes and core functionality. When you encounter issues:
- Copy error messages directly into the chat
- Be descriptive about what’s not working
- Provide clear requirements for new features
Example prompts for adding features:
Refining with Assistant
Switch to Assistant for detailed improvements and UI refinements. Use the @
symbol to reference specific files:
Use web development terms like “responsive,” “mobile-friendly,” and “grid interface” to communicate effectively.
Deploy your app
Start deployment
Select Publish or search for “Deployments” in the command bar.
Configure resources
For auto-scale deployments, configure:
- Basic resources (1 CPU, 1GB RAM per instance)
- Maximum machines (start with 6)
- Environment variables
- Run commands
Launch
- Name your app
- Select Deploy
- Wait 1-5 minutes for deployment
- Access your app via the provided URL
Best practices
Use Agent for
- Initial setup
- Core functionality
- Major structural changes
- Error resolution
Use Assistant for
- UI refinements
- Small feature additions
- Code optimization
- Documentation
Success with AI tools depends more on clear communication than coding expertise. Focus on describing your vision effectively using web development terminology.
