name: Write a string to a file
|
|
---
|
|
|
|
This code snippet writes a string to disk at a particular _absolute path_.
|
|
|
|
It uses the fast [`Bun.write()`](/docs/api/file-io#writing-files-bun-write) API to efficiently write data to disk. The first argument is a _destination_; the second is the _data_ to write.
|
|
|
|
```ts
|
|
const path = "/path/to/file.txt";
|
|
await Bun.write(path, "Lorem ipsum");
|
|
```
|
|
|

Any relative paths will be resolved relative to the project root (the nearest directory containing a `package.json` file).
|
|
|
|
```ts
|
|
const path = "./file.txt";
|
|
await Bun.write(path, "Lorem ipsum");
|
|
```
|
|

You can pass a `BunFile` as the destination. `Bun.write()` will write the data to its associated path.
|
|
|
|
```ts
|
|
const path = Bun.file("./file.txt");
|
|
await Bun.write(path, "Lorem ipsum");
|
|
```
|
|

|
`Bun.write()` returns the number of bytes written to disk.
|
|
|
|
```ts
|
|
const path = "./file.txt";
|
|
const bytes = await Bun.write(path, "Lorem ipsum");
|
|
// => 11
|
|
```
