Introducing React Doctor for Performance Fix slow React code and make it fast npx react-doctor@latest
The Hook
“(No spoken dialogue — The audio features a sustained, evolving pad sound, building tension.)”
Problem Agitation
“(No spoken dialogue — A distinct riser starts, peaking with a significant sub-bass drop/impact.)”
Product Reveal
“(No spoken dialogue — A rhythmic, pulsing synth bass line and a high-frequency arpeggiated synth melody begin.)”
Feature Teaser
“(No spoken dialogue — Another riser begins, culminating in a powerful sub-bass drop/impact.)”
Call to Action
“(No spoken dialogue — A bright, sustained synth chord and a subtle sweep effect accompany the final resolution.)”
Synthesizable in Remotion · key components of the terminal-dev-tool-launch template.
Text appears character by character, simulating typing, accompanied by a blinking vertical cursor at the end of the current text string.
Use `interpolate` to reveal text characters based on time. A `spring` animation can control the opacity and scale of a `Rectangle` component for the blinking cursor.
A list of text entries scrolls rapidly upwards, with specific lines highlighted in different colors (red for errors, yellow for warnings, green for resolved).
Implement a `Sequence` of `Text` components within a `Scroll` component. Use `interpolate` on the `translateY` property for the scrolling effect. Conditional styling based on data can change text and background colors for highlights.
A horizontal progress bar fills from left to right, displaying a numerical score and a descriptive text (e.g., 'Extremely slow', 'Fast'). An emoji icon changes its expression based on the score.
Use `interpolate` to animate the `width` of a `Rectangle` component for the progress bar. Conditional rendering or `interpolate` on `opacity` can switch between different SVG emoji components based on the score range. Text updates dynamically with the score.
Purpose. Immediately identifies and articulates the core problem faced by the target audience (slow React apps).
Execution. Typewriter animation of 'Slow React app?' on a black screen, creating a direct, relatable question.
Purpose. Visually demonstrates the process of identifying specific performance bottlenecks, agitating the problem.
Execution. Rapidly scrolling terminal log with highlighted problematic code lines, overlaid with 'Scan for slow renders'.
Purpose. Introduces the product as the solution, showing it actively fixing the identified problems and improving performance.
Execution. Terminal interface showing 'Make React Fast' command, 'Fixing issues...' text, and a progress bar increasing from 'Extremely slow' to 'Fast', with issues changing from red to green.
Purpose. Celebrates the successful resolution of the problem and directs the user to the product.
Execution. Progress bar reaching 100% with a happy emoji, confetti explosion, and the product URL displayed prominently.
Objective
A new CLI tool called 'SecureScan' that quickly identifies and fixes security vulnerabilities in Node.js applications.How the recipe adapts
The opening would feature 'Vulnerable Node.js app?' typed out. The problem agitation scene would show a fast-scrolling terminal log highlighting security flaws in red, with 'Scan for vulnerabilities' text. The product reveal would show 'SecureScan' running, fixing issues, and a progress bar moving from 'High Risk' to 'Secure', with a changing emoji. The call to action would be 'https://securescan.dev' with a confetti burst.Scene durations (5 scenes, 13.6s)
