jarle 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() API to efficiently write data to disk. The first argument is a destination; the second is the data to write.
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).
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.
const path = Bun.file("./file.txt");
await Bun.write(path, "Lorem ipsum");
Bun.write() returns the number of bytes written to disk.
const path = "./file.txt";
const bytes = await Bun.write(path, "Lorem ipsum");
// => 11
