How to use the move-file function in move-file

tempFileWriteStream.on('close', resolve)
                    tempFileWriteStream.on('error', reject)
                })

                // Load a `Database` from the file to check that it's valid.
                await new JsonDatabase().load(tempFile.path, () => noopTransformer)

                // Replace the old LSIF file with the new file.
                try {
                    await fs.mkdir(STORAGE_ROOT)
                } catch (e) {
                    if (e.code !== 'EEXIST') {
                        throw e
                    }
                }
                await moveFile(tempFile.path, diskKey({ repository, commit }))

                // Evict the old `Database` from the LRU cache to cause it to pick up the new LSIF data from disk.
                dbLRU.del(diskKey({ repository, commit }))

                res.send('Upload successful.')
            })
