Ensure File
Given some contents, ensure a file with those contents exists. Callback or return with the file's contents.
Usage
var ensureFile = require('ensure-file')
ensureFile('path/to/file.md', '# foo', function (err, contents) {
console.log(contents) // '# foo', or contents of existing file
})
// Synchronous version
var contents = ensureFile.sync('path/to/file.md', '# foo')
var ensureJsonFile = require('ensure-file/json')
ensureFileJson('path/to/file.json', { foo: 'bar' }, function (err, contents) {
console.log(contents) // { foo: 'bar' } or contents of existing file
})
// Synchronous version
var contents = ensureJsonFile.sync('path/to/file.md', { foo: 'bar' })API
ensureFile(path, contents, callback)
Looks for a file at path. If the file exists, calls callback with any error that occurred and the contents of the file. If a file doesn't exist at path, it will first create the file with the default contents before calling the callback with any error and the default contents.
ensureFile.sync(path, contents)
The same as ensureFile() but synchronous.
ensureJsonFile(path, contents, callback)
The same as ensureFile(), however the contents will be run through JSON.stringify before being written to file, and JSON.parse before being returned.
ensureJsonFile.sync(path, contents, callback)
The same as ensureJsonFile() but synchronous
