# read-package-json-fast
|
||
|
|
|
||
|
|
Like [`read-package-json`](http://npm.im/read-package-json), but faster and
|
||
|
|
more accepting of "missing" data.
|
||
|
|
|
||
|
|
This is only suitable for reading package.json files in a node_modules
|
||
|
|
tree, since it doesn't do the various cleanups, normalization, and warnings
|
||
|
|
that are beneficial at the root level in a package being published.
|
||
|
|
|
||
|
|
## USAGE
|
||
|
|
|
||
|
|
```js
|
||
|
|
const rpj = require('read-package-json-fast')
|
||
|
|
|
||
|
|
// typical promisey type API
|
||
|
|
rpj('/path/to/package.json')
|
||
|
|
.then(data => ...)
|
||
|
|
.catch(er => ...)
|
||
|
|
|
||
|
|
// or just normalize a package manifest
|
||
|
|
const normalized = rpj.normalize(packageJsonObject)
|
||
|
|
```
|
||
|
|
|
||
|
|
Errors raised from parsing will use
|
||
|
|
[`json-parse-even-better-errors`](http://npm.im/json-parse-even-better-errors),
|
||
|
|
so they'll be of type `JSONParseError` and have a `code: 'EJSONPARSE'`
|
||
|
|
property. Errors will also always have a `path` member referring to the
|
||
|
|
path originally passed into the function.
|
||
|
|
|
||
|
|
## WHAT THIS MODULE DOES
|
||
|
|
|
||
|
|
- Parse JSON
|
||
|
|
- Normalize `bundledDependencies`/`bundleDependencies` naming to just
|
||
|
|
`bundleDependencies` (without the extra `d`)
|
||
|
|
- Handle `true`, `false`, or object values passed to `bundleDependencies`
|
||
|
|
- Normalize `funding: <string>` to `funding: { url: <string> }`
|
||
|
|
- Remove any `scripts` members that are not a string value.
|
||
|
|
- Normalize a string `bin` member to `{ [name]: bin }`.
|
||
|
|
- Fold `optionalDependencies` into `dependencies`.
|
||
|
|
- Set the `_id` property if name and version are set. (This is
|
||
|
|
load-bearing in a few places within the npm CLI.)
|
||
|
|
|
||
|
|
## WHAT THIS MODULE DOES NOT DO
|
||
|
|
|
||
|
|
- Warn about invalid/missing name, version, repository, etc.
|
||
|
|
- Extract a description from the `README.md` file, or attach the readme to
|
||
|
|
the parsed data object.
|
||
|
|
- Read the `HEAD` value out of the `.git` folder.
|
||
|
|
- Warn about potentially typo'ed scripts (eg, `tset` instead of `test`)
|
||
|
|
- Check to make sure that all the files in the `files` field exist and are
|
||
|
|
valid files.
|
||
|
|
- Fix bundleDependencies that are not listed in `dependencies`.
|
||
|
|
- Fix `dependencies` fields that are not strictly objects of string values.
|
||
|
|
- Anything involving the `directories` field (ie, bins, mans, and so on).
