Usage:
49 + 50 +
pacote resolve <spec>
51 +
Resolve a specifier and output the fully resolved target
52 +
Returns integrity and from if '--long' flag is set.
53 + 54 +
pacote manifest <spec>
55 +
Fetch a manifest and print to stdout
56 + 57 +
pacote packument <spec>
58 +
Fetch a full packument and print to stdout
59 + 60 +
pacote tarball <spec> [<filename>]
61 +
Fetch a package tarball and save to <filename>
62 +
If <filename> is missing or '-', the tarball will be streamed to stdout.
63 + 64 +
pacote extract <spec> <folder>
65 +
Extract a package to the destination folder.
66 + 67 +
Configuration values all match the names of configs passed to npm, or
68 +
options passed to Pacote. Additional flags for this executable:
69 + 70 +
--long Print an object from 'resolve', including integrity and spec.
71 +
--json Print result objects as JSON rather than node's default.
72 +
(This is the default if stdout is not a TTY.)
73 +
--help -h Print this helpful text.
74 + 75 +
For example '--cache=/path/to/folder' will use that folder as the cache.
