### Start Developing
|
||||
|
||||
You can launch the package in dev-mode by running:
|
||||
|
||||
```shell
|
||||
pnpm dev
|
||||
```
|
||||
|
||||
This will use turbo to run all packages in watch-mode. This means you can make changes and have them automatically built.
|
||||
|
||||
If you want to customize what packages are built/watched, you can run turbo directly and adjust the filter:
|
||||
|
||||
```shell
|
||||
pnpm turbo run dev --filter="./packages/core" --concurrency=100
|
||||
```
|
||||
|
||||
In another terminal, you can write and run any script needed to quickly test your changes. For example:
|
||||
|
||||
```typescript
|
||||
import { createMemory, staticBlock } from "@llamaindex/core/memory";
|
||||
|
||||
// Create memory with predefined context
|
||||
const memory = createMemory({
|
||||
memoryBlocks: [
|
||||
staticBlock({
|
||||
content:
|
||||
"The user is a software engineer who loves TypeScript and LlamaIndex.",
|
||||
messageRole: "system",
|
||||
}),
|
||||
],
|
||||
});
|
||||
|
||||
async function main() {
|
||||
const result = await memory.getLLM();
|
||||
console.log(result);
|
||||
}
|
||||
|
||||
void main().catch(console.error);
|
||||
```
|
||||
|
||||
And run it with:
|
||||
|
||||
```shell
|
||||
pnpm exec tsx my_script.ts
|
||||
```
|
||||
|
||||
This flow allows you to easily test your changes without having to build the entire project.
|
||||
|
||||
Once you are happy with your changes, be sure to add tests (and confirm existing tests are passing!).

# LlamaIndexTS Examples

This package contains several examples of how to use LlamaIndexTS.

Before running any of the code examples,

make sure you have basic knowledge of the [LlamaIndexTS](https://ts.llamaindex.ai/).
