API

from(dirname): Promise<DirectoryIntegrity>

Returns a mapping of file names to size and Subresource Integrity of each file.

Result example:

{
 'test/fixtures/4/lib/bar.js':
   { generatingIntegrity: Promise<'sha512-1B0QjibzjRrYeSf79Hcy9T1t8KNt4cFpz//88geXTN6lDnUzMo+4o/MJDESUs884XdZ5EX4RLdzsJA8qeEV3lg=='>,
     size: 198 },
  'test/index.js':
   { generatingIntegrity: Promise<'sha512-X6ypBcefaTDbDHHcR0J57E2dvDv6vAVi7tHAhfDImmDU8LBaYwdkdX+hVlqFdWNevJjRqsgZbXb/c+Ewq5t3tQ=='>,
     size: 939 } }

check(dirname, directoryIntegrity): Promise<Boolean>

Verifies directory integrity against a directoryIntegrity argument.

E.g.:

check('dirname', {
 'test/fixtures/4/lib/bar.js':
   { integrity: 'sha512-1B0QjibzjRrYeSf79Hcy9T1t8KNt4cFpz//88geXTN6lDnUzMo+4o/MJDESUs884XdZ5EX4RLdzsJA8qeEV3lg==',
     size: 198 },
  'test/index.js':
   { integrity: 'sha512-X6ypBcefaTDbDHHcR0J57E2dvDv6vAVi7tHAhfDImmDU8LBaYwdkdX+hVlqFdWNevJjRqsgZbXb/c+Ewq5t3tQ==',
