--diff= [--diff=] +npm diff --diff= [--diff=] +``` + +### Description + +Similar to its `git diff` counterpart, this command will print diff patches +of files for packages published to the npm registry. + +* `npm diff --diff= --diff=` + + Compares two package versions using their registry specifiers, e.g: + `npm diff --diff=pkg@1.0.0 --diff=pkg@^2.0.0`. It's also possible to + compare across forks of any package, + e.g: `npm diff --diff=pkg@1.0.0 --diff=pkg-fork@1.0.0`. + + Any valid spec can be used, so that it's also possible to compare + directories or git repositories, + e.g: `npm diff --diff=pkg@latest --diff=./packages/pkg` + +* `npm diff` (in a package directory, no arguments): + + If the package is published to the registry, `npm diff` will fetch the + tarball version tagged as `latest` (this value can be configured using the + `tag` option) and proceed to compare the contents of files present in that + tarball, with the current files in your local file system. + + This workflow provides a handy way for package authors to see what + package-tracked files have been changed in comparison with the latest + published version of that package. + +* `npm diff --diff=` (in a package directory): + + When using a single package name (with no version or tag specifier) as an + argument, `npm diff` will work in a similar way to + [`npm-outdated`](npm-outdated) and reach for the registry to figure out + what current published version of the package named will satisfy + its dependent declared semver-range. Once that specific version is known + `npm diff` will print diff patches comparing the current version of + found in the local file system with that specific version + returned by the registry. + +* `npm diff --diff=` (in a package directory): + + Similar to using only a single package name, it's also possible to declare + a full registry specifier version if you wish to compare the local version + of a installed package with the specific version/tag/semver-range provided + in ``. e.g: (assuming pkg@1.0.0 is installed in the current + `node_modules` folder) running `npm diff --diff=pkg@2.0.0` will effectively + be an alias to `npm diff --diff=pkg@1.0.0 --diff=pkg@2.0.0`. + +* `npm diff --diff= [--diff=]` (in a package directory): + + Using `npm diff` along with semver-valid version numbers is a shorthand + to compare different versions of the current package. It needs to be run + from a package directory, such that for a package named `pkg` running + `npm diff --diff=1.0.0 --diff=1.0.1` is the same as running + `npm diff --diff=pkg@1.0.0 --diff=pkg@1.0.1`. If only a single argument + `` is provided, then the current local file system is going to + be compared against that version. + +Note that tag names are not valid `--diff` argument values, if you wish to +compare against a published tag, you must use the `pkg@tagname` syntax. + +#### Filtering files + +It's possible to also specify positional arguments using file names or globs +pattern matching in order to limit the result of diff patches to only a subset +of files for a given package, e.g: + +`npm diff --diff=pkg@2 ./lib/ CHANGELOG.md` + +### Configuration + +#### diff + +* Type: String, Array, null +* Default: null + +Defines up to two npm valid package specifiers in which to compare. + +#### diff-name-only + +* Type: Boolean +* Default: false + +When set to `true` running `npm diff` only returns the names of the files that +have any difference. + +#### diff-unified + +* Type: number +* Default: `3` + +The number of lines of context to print in the unified diff format output. + +#### diff-ignore-all-space + +* Type: Boolean +* Default: false + +Ignore whitespace when comparing lines.

Currently, only `context` is supported and describes how many lines of context should be included. + +* `Diff.createPatch(fileName, oldStr, newStr, oldHeader, newHeader)` - creates a unified diff patch. + + Just like Diff.createTwoFilesPatch, but with oldFileName being equal to newFileName. + + +* `Diff.structuredPatch(oldFileName, newFileName, oldStr, newStr, oldHeader, newHeader, options)` - returns an object with an array of hunk objects. + + This method is similar to createTwoFilesPatch, but returns a data structure + suitable for further processing. Parameters are the same as createTwoFilesPatch. The data structure returned may look like this: + + ```js + { + oldFileName: 'oldfile', newFileName: 'newfile', + oldHeader: 'header1', newHeader: 'header2', + hunks: [{ + oldStart: 1, oldLines: 3, newStart: 1, newLines: 3, + lines: [' line2', ' line3', '-line4', '+line5', '\\ No newline at end of file'], + }] + } + ``` + +* `Diff.applyPatch(source, patch[, options])` - applies a unified diff patch. + + Return a string containing new version of provided data. `patch` may be a string diff or the output from the `parsePatch` or `structuredPatch` methods. + + The optional `options` object may have the following keys: + + - `fuzzFactor`: Number of lines that are allowed to differ before rejecting a patch. Defaults to 0. + - `compareLine(lineNumber, line, operation, patchContent)`: Callback used to compare to given lines to determine if they should be considered equal when patching. Defaults to strict equality but may be overridden to provide fuzzier comparison. Should return false if the lines should be rejected. + +* `Diff.applyPatches(patch, options)` - applies one or more patches. + + This method will iterate over the contents of the patch and apply to data provided through callbacks. The general flow for each patch index is: + + - `options.loadFile(index, callback)` is called. The caller should then load the contents of the file and then pass that to the `callback(err, data)` callback. Passing an `err` will terminate further patch execution. + - `options.patched(index, content, callback)` is called once the patch has been applied. `content` will be the return value from `applyPatch`. When it's ready, the caller should call `callback(err)` callback. Passing an `err` will terminate further patch execution. + + Once all patches have been applied or an error occurs, the `options.complete(err)` callback is made. + +* `Diff.parsePatch(diffStr)` - Parses a patch into structured data + + Return a JSON object representation of the a patch, suitable for use with the `applyPatch` method. This parses to the same structure returned by `Diff.structuredPatch`. + +* `convertChangesToXML(changes)` - converts a list of changes to a serialized XML format + + +All methods above which accept the optional `callback` method will run in sync mode when that parameter is omitted and in async mode when supplied. This allows for larger diffs without blocking the event loop. This may be passed either directly as the final parameter or as the `callback` field in the `options` object. + +### Change Objects +Many of the methods above return change objects. These objects consist of the following fields: + +* `value`: Text content +* `added`: True if the value was inserted into the new string +* `removed`: True if the value was removed from the old string + +Note that some cases may omit a particular flag field.

+## Compatibility
+
+[![Sauce Test Status](https://saucelabs.com/browser-matrix/jsdiff.svg)](https://saucelabs.com/u/jsdiff)
+
+jsdiff supports all ES3 environments with some known issues on IE8 and below. Under these browsers some diff algorithms such as word diff and others may fail due to lack of support for capturing groups in the `split` operation.
