Function: outputFile()
Call Signature
outputFile(
file
,data
,options
?):Promise
<void
>
Defined in: packages/node/src/fs.ts:12
Almost the same as writeFile
(i.e. it overwrites), except that if the parent directory does not exist, it's created.
Parameters
file
string
data
string
| ArrayBufferView
<ArrayBufferLike
>
options?
WriteFileOptions
Returns
Promise
<void
>
Example
import * as fs from 'fs-extra'
const file = '/tmp/this/path/does/not/exist/file.txt'
// With a callback:
fs.outputFile(file, 'hello!', err => {
console.log(err) // => null
fs.readFile(file, 'utf8', (err, data) => {
if (err) return console.error(err)
console.log(data) // => hello!
})
})
// With Promises:
fs.outputFile(file, 'hello!')
.then(() => fs.readFile(file, 'utf8'))
.then(data => {
console.log(data) // => hello!
})
.catch(err => {
console.error(err)
})
// With async/await:
async function asyncAwait () {
try {
await fs.outputFile(file, 'hello!')
const data = await fs.readFile(file, 'utf8')
console.log(data) // => hello!
} catch (err) {
console.error(err)
}
