|
| 48 | +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. |
