jonschlinkert/write: Write data to the file system, creating any intermediate directories if they don't already exist. Used by flat-cache and many others!

Write data to a file, replacing the file if it already exists and creating any intermediate directories if they don't already exist. Thin wrapper around node's native fs methods.

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your ❤️ and support.

Install with npm (requires Node.js >=10):

$ npm install --save write

const write = require('write');

The following options may be used with any method.

Type: boolean

Default: undefined

Ensure that contents has a trailing newline before writing it to the file system.

write.sync('foo.txt', 'some data...', { newline: true });

Type: boolean

Default: undefined

Set to false to prevent existing files from being overwritten. See increment for a less severe alternative.

write.sync('foo.txt', 'some data...', { overwrite: false });

Type: boolean

Default: undefined

Set to true to automatically rename files by appending an increment, like foo (2).txt, to prevent foo.txt from being overwritten. This is useful when writing log files, or other information where the file name is less important than the contents being written.

write.sync('foo.txt', 'some data...', { increment: true });
// if "foo.txt" exists, the file will be renamed to "foo (2).txt"

Asynchronously writes data to a file, replacing the file if it already exists and creating any intermediate directories if they don't already exist. Data can be a string or a buffer. Returns a promise if a callback function is not passed.

Params

filepath {String}: file path.
data {String|Buffer|Uint8Array}: Data to write.
options {Object}: Options to pass to fs.writeFile
callback {Function}: (optional) If no callback is provided, a promise is returned.
returns {Object}: Returns an object with the path and contents of the file that was written to the file system. This is useful for debugging when options.increment is used and the path might have been modified.

Example

const write = require('write');

// async/await
(async () => {
  await write('foo.txt', 'This is content...');
})();

// promise
write('foo.txt', 'This is content...')
  .then(() => {
    // do stuff
  });

// callback
write('foo.txt', 'This is content...', err => {
  // do stuff with err
});

The synchronous version of write. Returns undefined.

Params

filepath {String}: file path.
data {String|Buffer|Uint8Array}: Data to write.
options {Object}: Options to pass to fs.writeFileSync
returns {Object}: Returns an object with the path and contents of the file that was written to the file system. This is useful for debugging when options.increment is used and the path might have been modified.

Example

const write = require('write');
write.sync('foo.txt', 'This is content...');

Returns a new WriteStream object. Uses fs.createWriteStream to write data to a file, replacing the file if it already exists and creating any intermediate directories if they don't already exist. Data can be a string or a buffer.

Params

filepath {String}: file path.
options {Object}: Options to pass to fs.createWriteStream
returns {Stream}: Returns a new WriteStream object. (See Writable Stream).

Example

const fs = require('fs');
const write = require('write');
fs.createReadStream('README.md')
  .pipe(write.stream('a/b/c/other-file.md'))
  .on('close', () => {
    // do stuff
  });
