Web & Javascript: Learning by Building with Cursor AI

Hello! Students of the Cursor course.

Weekend Coding.

I was prepared for this when creating the course, but I didn't expect Cursor's feature update speed to be this fast 😭😭

(I'm starting to think I shouldn't have released this course...)

Cursor still appears to be the number one player in the IDE market.

I tried working on a single project using various IDEs in my own way.

I've tried Windsurf, Warp, and even Google's Antigravity

I still think Cursor is the best for comfortably using various features while switching between models.

When a new model is released, they apply it very quickly, and sometimes they even offer a week of free access to the latest model.

The most legendary update this time appears to be in the "Frontend" area.

It shows the browser layout and allows you to view and modify it in real-time.

It will be a very useful feature for developers in that it immediately shows the properties being changed.

Other changes include an updated plan mode and the addition of multi-agent evaluation.

Based on v2.2, I plan to update the course to cover the browser layout, plan mode, and the newly added Agent tab.

I will become the #1 Cursor-related course on Inflearn by continuously tracking updates until the end.

Later, if Cursor falls behind in the market or an overwhelmingly superior IDE emerges, I plan to stop updating the course,

Until then, please continue taking the course steadily..^^

+) Additionally, Stanford University in the United States has created a new computer science course called "The Modern Software Developer." I noticed it includes a significant amount of content on Agent coding and development using LLMs. I highly recommend reading through it. (Check out the Syllabus section)

https://themodernsoftware.dev/

The Cursor team announced Cursor version 2.0 on October 29th.

It's only been a few days since I updated the course based on v1.7, and it's already changed like this.

I am also someone who looks forward to new features and studies diligently,

I'm happy that LLM-based code editors are constantly evolving.

As a developer, you can expect greater productivity, and it becomes an opportunity for individuals to make a significant impact on society.

I gave 2 major presentations.

The first one is Composer, which was announced.

It is said to be the most advanced model that is 4 times faster than models of equivalent intelligence.

The second is the multi-agent interface.

Now they say the editor is designed with an agent-centric approach rather than a file-centric one, providing a more focused environment. While there are concerns about whether LLMs can accurately determine which tools to execute to perform tasks, I think this update suggests that an agent-based world will eventually arrive.

Additionally, they say that by utilizing git worktrees or remote machines, multiple agents can now run in parallel without interference.

You can check the detailed information below.

Hello,

Fellow students who are working hard on development today as well.

The competition in the LLM code editor market is becoming fiercer day by day.

However, I still think that Cursor has the fastest feature updates and is ahead of the competition.

I removed the previous version 0.48 video and updated it with a newly recorded video featuring significantly changed functionality.

Most major features have been updated, except for Plan mode and the context provision feature through @commands.

I plan to continue maintaining this as an improving course going forward,

Please take many courses and ask many questions so that you can work on more projects through Cursor.

Thank you.

1. Course Update Notice

Hello, students of Web & JS: Learn by Building with Cursor.

I recently uploaded all the final project (quiz) content, but then took the videos down again.

When I started this course, Cursor was at version 0.5xx, but it has now reached version 1.7.

There have been numerous advancements in LLM models during this time.

Claude Sonnet 4.5 version has been released, and the GPT-5 with Grok Code fast model has been released.

Various features such as Background Agent, MCP, Todo, Plan, Cursor CLI, and more have been added to Cursor during this time

I didn't have time to cover it in earnest. So I'm planning to proceed with an overall Update of the lecture.

I used to be a native Android app developer in the past, and these days I'm developing SaaS as a full-stack developer.

Through various experiences, I realized that the basic projects I had uploaded did not meet the course quality standards I had set for myself.

So I'm planning to systematically create and update projects on a larger scale.

This course was originally planned to have its price increased after completion, so

It would have been personally better to finish quickly and raise the price, but

I'm not going to upload this course for just a day or two and then stop

As AI tools continue to develop, I plan to keep improving and maintaining it, so for my future self as well

I concluded that it would be better to upload videos in a more specific and systematic manner.

Therefore, I plan to upload the final project with more specific chapter organization,

Section 12 (Web APIs), which is not a hands-on project, is scheduled to be fully uploaded within this week.

2. Upload Schedule (in order of priority)

1. Web APIs: ~by October

2. Project Three: ~November 31st

3. Section 7 - Complete update of Cursor features to the latest version: Mid-November

3. Additional lecture chapters planned

In addition to this, I plan to add chapters to this course by uploading text files containing prompt writing methods and prompt examples.

After completing the course to the quality I want, I plan to increase the course price to around 150,000-160,000 won.

4. Others

After completing the frontend area with this course, we plan to release courses on writing server-side (backend) programs and full-stack courses.

I believe that in the AI era, everyone will eventually be able to create their own services in the long term

As someone who first encountered software development, I want to contribute to making every individual an entrepreneur.

Words of Apology

Finally, I sincerely apologize for the continued delays in video uploads.

We deeply apologize and will ensure that the challenges and hearts of all those who made payments are not wasted

I will do my best to create a video that visualizes and explains in detail everything I know.

Thank you to everyone who always supports us, and I hope you have a happy holiday.

Cursor AI uploads its own update log at https://www.cursor.com/changelog .

For those who find it difficult to follow up, I am sharing a translated version.

Streamlined pricing, background agent, and new inline editing

Introducing on-demand unified pricing, Max mode available on all top-tier models, and background agents for parallel tasks.
You'll also find a variety of improvements, including more convenient context management with @folders , Inline Edit with more options, faster file editing, multi-root workspace support, and chat with export and duplicate features.

1. Simpler integrated pricing

We've unified our pricing structure to reduce confusion and reflect your feedback.

• All model usage is unified in Request units .

• Max mode changes to token-based billing (similar to the Model API method).

• Premium tool calls and long context mode have been removed for simplicity.

• The quotas and slow requests benefits of Hobby/Pro/Business plans remain the same.

• All usage details can be checked on the dashboard, making it easy to manage expenses.

2. Max mode for all top models

Max mode is available on all state-of-the-art models of Cursor.
Even when new models are added, you can immediately enjoy maximum performance in Max mode.

• When do you use it?

  • When broader context, higher intelligence, and tool utilization are essential

  • Complex problem solving or large-scale refactoring, etc.

• Charging method : Charging in proportion to the number of tokens used

• NOTE : Older versions of Cursor will still be able to use the old MAX version and long context mode for a while, but support will end soon. We recommend updating to the latest version.

Learn more about Max Mode

3. New Tab Model

We trained a new Tab model to be able to suggest changes across multiple files.

• Specialization areas : refactoring, edit chains, multi-file editing, jumping between related code

• Experience : More natural and faster completion suggestions

• Bonus : Added grammar highlighting to completion suggestions

4. Background Agent (Preview)

Agents can run in the background to process multiple tasks in parallel .

• Each agent operates in its own remote environment.

• Track progress, send follow-up messages, and take direct control

• In internal testing, it's been useful for "minor fixes", "investigative work", and "writing medium-sized PR drafts".

Learn more about Background Agent

5. Putting the entire codebase into context

• When using @folders , you can add the entire folder as context.

• Settings ▸ Full folder contents must be enabled

• If the folder/file is too large, it will be displayed as a small icon in the context pill.

6. New inline editing (Cmd/Ctrl + K)

• UI improvements and new options added

  • Edit entire file (⌘⇧⏎)

  • Send selection code block to agent (⌘L)

• For simple range changes, send to an agent for full file edits, or for multi-file edits or more granular control .

7. Edit long files quickly

Added a search & replace tool to the agent.

• Find and modify only the necessary parts without reading the entire file, even in long files

• Example) Approximately 2x speedup when editing Postgres codebase

• Applied from the Anthropic model, to be expanded in the future

8. Multi-root workspace

Work on multiple codebases in one space.

• Add multiple folders to one workspace → Index all

• Ideal for working on different projects simultaneously

• .cursor/rules is also supported in all folders

9. Enhanced chat function

Feature Description Export Chat Export to Markdown file from chat screen – including text and code blocks Duplicate Chat Right-click on the message ⋯ menu → Duplicate to New Chat to experiment with different branches of conversation flow

Other Matters

Shortcuts

Edit entire file in inline editing with shortcut keys Cmd / Ctrl + Shift + K

Improvements

1. Agent uses native terminal emulation (instead of the traditional virtual terminal approach)

2. @folders : Attempts to automatically include all files that can fit into the context.

3. Context status icons : See at a glance if a file is missing or abbreviated in the chat

4. You can disable individual MCP tools in MCP settings

5. New C# extensions released on the Marketplace

6. You can increase the chat font size in settings

7. Detailed changelog available within the app

Patch

Version Status Highlights 0.50.1 Pre-release Background Agent Available

Hello, this is Weekend Coding.

These days, Cursor AI updates are getting faster and faster, and the web development ecosystem is also changing rapidly.

We plan to re-film and upload previously filmed exchange rate projects and quiz site developments using the new Cursor AI version.

In addition, in the case of the exchange rate API provided by the Korea Export-Import Bank, calls cannot be made directly from the client due to the CORS policy, so we are improving the project by using Google's server through Google Apps Script.

In order to present better lecture videos and quality project development practice , the video that was scheduled to be uploaded at the end of April was postponed.

The upload period has been extended to late May to early June .

We ask for your understanding, but the price of this course was scheduled to increase after the upload at the end of May.

Due to the extension of the video upload date, we will be increasing prices starting in June.

This is to provide maximum benefits to those who purchase before the course is completed.

If you would like to purchase, please make your purchase in advance.

I will always do my best to provide lectures with good content. Thank you.
