## 📝 Summary
`bumpgen` bumps your dependencies and makes code changes for you if anything breaks.

This may be a common scenario:
`bumpgen` bumps your **TypeScript / TSX** dependencies and makes code changes for you if anything breaks.

> you: "I should upgrade to the latest version of x, it has banging new features and impressive performance improvments"
![demo](<https://assets-global.website-files.com/65af8f02f12662528cdc93d6/662e6061d42954630a191417_tanstack-ezgif.com-speed%20(1).gif>)

Here's a common scenario:

> you: "I should upgrade to the latest version of x, it has banging new features and impressive performance improvements"
>
> you (internal monologue): _I don't want to feel pain anymore_
> you (5 minutes later): _nevermind, that broke a bunch of stuff_

Then use `bumpgen`!

**How does it work?**

- It uses [ts-morph](https://github.com/dsherret/ts-morph) to turn your codebase into an AST to understand code relationships
- Uses the AST to get type definitions for external methods to understand how to use new package versions
- Creates a plan graph DAG to execute things in the correct order to get to the root of problems (ref: [arxiv 2309.12499](https://huggingface.co/papers/2309.12499))

![demo](https://s3.amazonaws.com/static.xeol.io/mkdirp-demo-optimized.gif)
- `bumpgen` builds your project to understand what broke when a dependency was bumped
- Then `bumpgen` uses [ts-morph](https://github.com/dsherret/ts-morph) to create an _abstract syntax tree_ from your code, to understand the relationships between statements
- It also uses the AST to get type definitions for external methods to understand how to use new package versions
- `bumpgen` then creates a _plan graph_ DAG to execute things in the correct order to handle propagating changes (ref: [arxiv 2309.12499](https://huggingface.co/papers/2309.12499))

## 🚀 Get Started

To get started, you'll need an OpenAI API key. `gpt-4-turbo-preview` from OpenAI is the only supported model at this time.

You can also run `bumpgen` without arguments and select which package to upgrade from the menu. Use `bumpgen --help` for a complete list of options.

## Limitations

There are some limitations you should know about.

- `bumpgen` can't handle multiple packages at this time. It will fail to upgrade packages that require peer dependencies to be updated the same time to work such as `@octokit/core` and `@octokit/plugin-retry`.
- `bumpgen` relies on build errors to determine what needs to be fixed. If an issue is caused by a behavioral change, `bumpgen` won't detect it.
- `bumpgen` can't handle multiple packages at the same time. It will fail to upgrade packages that require peer dependencies to be updated the same time to work such as `@octokit/core` and `@octokit/plugin-retry`.
- `bumpgen` is not good with very large frameworks like `vue`. These kind of upgrades (and vue 2 -> 3 specifically) can be arduous even for a human.

#### Abstract Syntax Tree

The AST is generated from **[ts-morph](https://github.com/dsherret/ts-morph)**. This AST allows `bumpgen` to understand the relationship between code properties in a codebase.

#### Plan Graph

The plan graph is a concept detailed in **[codeplan](https://huggingface.co/papers/2309.12499)** by Microsoft. The plan graph allows `bumpgen` to not only fix an issue at a point but also fix the 2nd order breaking changes from the fix itself. In short, it allows `bumpgen` to perpetuate a fix to the rest of the codebase.

#### Prompt Context

We pass the plan graph, the error, and the actual file with the breaking change as context to the LLM to maximize it's ability to fix the issue.
