# Simple Git

[![NPM version](https://img.shields.io/npm/v/simple-git.svg)](https://www.npmjs.com/package/simple-git)

A lightweight interface for running `git` commands in any [node.js](https://nodejs.org) application.

# Version 3 - Out Now

From v3 of `simple-git` you can now import as an ES module, Common JS module or as TypeScript with bundled type
definitions. Upgrading from v2 will be seamless for any application not relying on APIs that were marked as deprecated
in v2 (deprecation notices were logged to `stdout` as `console.warn` in v2).

# Installation

Use your favourite package manager:

-  [npm](https://npmjs.org): `npm install simple-git`
-  [yarn](https://yarnpkg.com/): `yarn add simple-git`

# System Dependencies

Requires [git](https://git-scm.com/downloads) to be installed and that it can be called using the command `git`.

# Usage

Include into your JavaScript app using common js:

```javascript
// require the library, main export is a function
const simpleGit = require('simple-git');
simpleGit().clean(simpleGit.CleanOptions.FORCE);

// or use named properties
const { simpleGit, CleanOptions } = require('simple-git');
simpleGit().clean(CleanOptions.FORCE);
```

Include into your JavaScript app as an ES Module:

```javascript
import { simpleGit, CleanOptions } from 'simple-git';

simpleGit().clean(CleanOptions.FORCE);
```

Include in a TypeScript app using the bundled type definitions:

```typescript
import { simpleGit, SimpleGit, CleanOptions } from 'simple-git';

const git: SimpleGit = simpleGit().clean(CleanOptions.FORCE);
```

## Configuration

Configure each `simple-git` instance with a properties object passed to the main `simpleGit` function:

```typescript
import { simpleGit, SimpleGit, SimpleGitOptions } from 'simple-git';

const options: Partial<SimpleGitOptions> = {
   baseDir: process.cwd(),
   binary: 'git',
   maxConcurrentProcesses: 6,
   trimmed: false,
};

// when setting all options in a single object
const git: SimpleGit = simpleGit(options);

// or split out the baseDir, supported for backward compatibility
const git: SimpleGit = simpleGit('/some/path', { binary: 'git' });
```

The first argument can be either a string (representing the working directory for `git` commands to run in),
`SimpleGitOptions` object or `undefined`, the second parameter is an optional `SimpleGitOptions` object.

All configuration properties are optional, the default values are shown in the example above.

## Per-command Configuration

To prefix the commands run by `simple-git` with custom configuration not saved in the git config (ie: using the
`-c` command) supply a `config` option to the instance builder:

```typescript
// configure the instance with a custom configuration property
const git: SimpleGit = simpleGit('/some/path', { config: ['http.proxy=someproxy'] });

// any command executed will be prefixed with this config
// runs: git -c http.proxy=someproxy pull
await git.pull();
```

## Configuring Plugins

- [AbortController](https://github.com/steveukx/git-js/blob/main/docs/PLUGIN-ABORT-CONTROLLER.md)
   Terminate pending and future tasks in a `simple-git` instance (requires node >= 16).

- [Completion Detection](https://github.com/steveukx/git-js/blob/main/docs/PLUGIN-COMPLETION-DETECTION.md)
   Customise how `simple-git` detects the end of a `git` process.

- [Error Detection](https://github.com/steveukx/git-js/blob/main/docs/PLUGIN-ERRORS.md)
   Customise the detection of errors from the underlying `git` process.

- [Progress Events](https://github.com/steveukx/git-js/blob/main/docs/PLUGIN-PROGRESS-EVENTS.md)
   Receive progress events as `git` works through long-running processes.

- [Spawned Process Ownership](https://github.com/steveukx/git-js/blob/main/docs/PLUGIN-SPAWN-OPTIONS.md)
   Configure the system `uid` / `gid` to use for spawned `git` processes.

- [Timeout](https://github.com/steveukx/git-js/blob/main/docs/PLUGIN-TIMEOUT.md)
   Automatically kill the wrapped `git` process after a rolling timeout.

- [Unsafe](https://github.com/steveukx/git-js/blob/main/docs/PLUGIN-UNSAFE-ACTIONS.md)
   Selectively opt out of `simple-git` safety precautions - for advanced users and use cases.

## Using Task Promises

Each task in the API returns the `simpleGit` instance for chaining together multiple tasks, and each
step in the chain is also a `Promise` that can be `await` ed in an `async` function or returned in a
`Promise` chain.

```javascript
const git = simpleGit();

// chain together tasks to await final result
await git.init().addRemote('origin', '...remote.git');

// or await each step individually
await git.init();
await git.addRemote('origin', '...remote.git');
```

### Catching errors in async code

To catch errors in async code, either wrap the whole chain in a try/catch:

```javascript
const git = simpleGit();
try {
   await git.init();
   await git.addRemote(name, repoUrl);
} catch (e) {
   /* handle all errors here */
}
```

or catch individual steps to permit the main chain to carry on executing rather than
jumping to the final `catch` on the first error:

```javascript
const git = simpleGit();
try {
   await git.init().catch(ignoreError);
   await git.addRemote(name, repoUrl);
} catch (e) {
   /* handle all errors here */
}

function ignoreError() {}
```

## Using Task Callbacks

In addition to returning a promise, each method can also be called with a trailing callback argument
to handle the result of the task.

```javascript
const git = simpleGit();
git.init(onInit).addRemote('origin', 'git@github.com:steveukx/git-js.git', onRemoteAdd);

function onInit(err, initResult) {}
function onRemoteAdd(err, addRemoteResult) {}
```

If any of the steps in the chain result in an error, all pending steps will be cancelled, see the
[parallel tasks](<(#concurrent--parallel-requests)>) section for more information on how to run tasks in parallel rather than in series .

## Task Responses

Whether using a trailing callback or a Promise, tasks either return the raw `string` or `Buffer` response from the
`git` binary, or where possible a parsed interpretation of the response.

For type details of the response for each of the tasks, please see the [TypeScript definitions](https://github.com/steveukx/git-js/blob/main/simple-git/typings/simple-git.d.ts).

## changing the working directory [examples](https://github.com/steveukx/git-js/blob/main/examples/git-change-working-directory.md)

-  `.cwd(workingDirectory)` Sets the working directory for all future commands - note, this will change the working for the root instance, any chain created from the root will also be changed.
-  `.cwd({ path, root = false })` Sets the working directory for all future commands either in the current chain of commands (where `root` is omitted or set to `false`) or in the main instance (where `root` is `true`).

## How to Specify Options

Where the task accepts custom options (eg: `pull` or `commit`), these can be supplied as an object, the keys of which
will all be merged as trailing arguments in the command string, or as a simple array of strings.

### Options as an Object

When the value of the property in the options object is a `string`, that name value
pair will be included in the command string as `name=value`. For example:

```javascript
// results in 'git pull origin master --no-rebase'
git.pull('origin', 'master', { '--no-rebase': null });

// results in 'git pull origin master --rebase=true'
git.pull('origin', 'master', { '--rebase': 'true' });
```

### Options as an Array

Options can also be supplied as an array of strings to be merged into the task's commands
in the same way as when an object is used:

```javascript
// results in 'git pull origin master --no-rebase'
git.pull('origin', 'master', ['--no-rebase']);
```

# Release History

Major release 3.x changes the packaging of the library, making it consumable as a CommonJS module, ES module as well as
with TypeScript (see [usage](#usage) above). The library is now published as a single file, so please ensure your
application hasn't been making use of non-documented APIs by importing from a sub-directory path.

See also:

- [release notes v3](https://github.com/steveukx/git-js/blob/main/simple-git/CHANGELOG.md)
- [release notes v2](https://github.com/steveukx/git-js/blob/main/docs/RELEASE-NOTES-V2.md)

# Concurrent / Parallel Requests

When the methods of `simple-git` are chained together, they create an execution chain that will run in series, useful
for when the tasks themselves are order-dependent, eg:

```typescript
simpleGit().init().addRemote('origin', 'https://some-repo.git').fetch();
```

Each task requires that the one before it has been run successfully before it is called, any errors in a
step of the chain should prevent later steps from being attempted.

When the methods of `simple-git` are called on the root instance (ie: `git = simpleGit()`) rather than chained
off another task, it starts a new chain and will not be affected failures in tasks already being run. Useful
for when the tasks are independent of each other, eg:

```typescript
const git = simpleGit();
const results = await Promise.all([
   git.raw('rev-parse', '--show-cdup').catch(swallow),
   git.raw('rev-parse', '--show-prefix').catch(swallow),
]);
function swallow(err) {
   return null;
}
```

Each `simple-git` instance limits the number of spawned child processes that can be run simultaneously and
manages the queue of pending tasks for you. Configure this value by passing an options object to the
`simpleGit` function, eg:

```typescript
const git = simpleGit({ maxConcurrentProcesses: 10 });
```

Treating tasks called on the root instance as the start of separate chains is a change to the behaviour of
`simple-git` and was added in version `2.11.0`.

# Complex Requests

When no suitable wrapper exists in the interface for creating a request, run the command directly
using `git.raw([...], handler)`. The array of commands are passed directly to the `git` binary:

```javascript
const path = '/path/to/repo';
const commands = ['config', '--global', 'advice.pushNonFastForward', 'false'];

// using an array of commands and node-style callback
simpleGit(path).raw(commands, (err, result) => {
   // err is null unless this command failed
   // result is the raw output of this command
});

// using a var-args of strings and awaiting rather than using the callback
const result = await simpleGit(path).raw(...commands);

// automatically trim trailing white-space in responses
const result = await simpleGit(path, { trimmed: true }).raw(...commands);
```

# Authentication

The easiest way to supply a username / password to the remote host is to include it in the URL, for example:

```javascript
const USER = 'something';
const PASS = 'somewhere';
const REPO = 'github.com/username/private-repo';

const remote = `https://${USER}:${PASS}@${REPO}`;

simpleGit()
   .clone(remote)
   .then(() => console.log('finished'))
   .catch((err) => console.error('failed: ', err));
```

Be sure to not enable debug logging when using this mechanism for authentication
to ensure passwords aren't logged to stdout.

# Environment Variables

Pass one or more environment variables to the child processes spawned by `simple-git` with the `.env` method which
supports passing either an object of name=value pairs or setting a single variable at a time:

```javascript
const GIT_SSH_COMMAND = 'ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no';

simpleGit()
   .env('GIT_SSH_COMMAND', GIT_SSH_COMMAND)
   .status((err, status) => {
      /*  */
   });

simpleGit()
   .env({ ...process.env, GIT_SSH_COMMAND })
   .status()
   .then((status) => {})
   .catch((err) => {});
```

Note - when passing environment variables into the child process, these will replace the standard `process.env`
variables, the example above creates a new object based on `process.env` but with the `GIT_SSH_COMMAND` property added.

# Exception Handling

When the `git` process exits with a non-zero status (or in some cases like `merge` the git process exits with a
successful zero code but there are conflicts in the merge) the task will reject with a `GitError` when there is no
available parser to handle the error or a
`GitResponseError` for when there is.

See the `err` property of the callback:

```javascript
git.merge((err, mergeSummary) => {
   if (err.git) {
      mergeSummary = err.git; // the failed mergeSummary
   }
});
```

Catch errors with try/catch in async code:

```javascript
try {
   const mergeSummary = await git.merge();
   console.log(`Merged ${mergeSummary.merges.length} files`);
} catch (err) {
   // err.message - the string summary of the error
   // err.stack - some stack trace detail
   // err.git - where a parser was able to run, this is the parsed content

   console.error(`Merge resulted in ${err.git.conflicts.length} conflicts`);
}
```

Catch errors with a `.catch` on the promise:

```javascript
const mergeSummary = await git.merge().catch((err) => {
   if (err.git) {
      return err.git;
   } // the unsuccessful mergeSummary
   throw err; // some other error, so throw
});

if (mergeSummary.failed) {
   console.error(`Merge resulted in ${mergeSummary.conflicts.length} conflicts`);
}
```

With typed errors available in TypeScript

```typescript
import { simpleGit, MergeSummary, GitResponseError } from 'simple-git';
try {
   const mergeSummary = await simpleGit().merge();
   console.log(`Merged ${mergeSummary.merges.length} files`);
} catch (err) {
   // err.message - the string summary of the error
   // err.stack - some stack trace detail
   // err.git - where a parser was able to run, this is the parsed content
   const mergeSummary: MergeSummary = (err as GitResponseError<MergeSummary>).git;
   const conflicts = mergeSummary?.conflicts || [];

   console.error(`Merge resulted in ${conflicts.length} conflicts`);
}
```

# Troubleshooting / FAQ

### Enable logging

See the [debug logging guide](https://github.com/steveukx/git-js/blob/main/docs/DEBUG-LOGGING-GUIDE.md) for logging examples and how to
make use of the [debug](https://www.npmjs.com/package/debug) library's programmatic interface
in your application.

### Enable Verbose Logging

See the [debug logging guide](https://github.com/steveukx/git-js/blob/main/docs/DEBUG-LOGGING-GUIDE.md#verbose-logging-options) for
the full list of verbose logging options to use with the
[debug](https://www.npmjs.com/package/debug) library.

### Every command returns ENOENT error message

There are a few potential reasons:

-  `git` isn't available as a binary for the user running the main `node` process, custom paths to the binary can be used
   with the `.customBinary(...)` api option.

-  the working directory passed in to the main `simple-git` function isn't accessible, check it is read/write accessible
   by the user running the `node` process. This library uses
   [@kwsites/file-exists](https://www.npmjs.com/package/@kwsites/file-exists) to validate the working directory exists,
   to output its logs add `@kwsites/file-exists` to your `DEBUG` environment variable. eg:

   `DEBUG=@kwsites/file-exists,simple-git node ./your-app.js`

### Log format fails

The properties of `git log` are fetched using the `--pretty=format` argument which supports different tokens depending
on the version of `git` - for example the `%D` token used to show the refs was added in git `2.2.3`, for any version
before that please ensure you are supplying your own format object with properties supported by the version of git you
are using.

For more details of the supported tokens, please see the
[official `git log` documentation](https://git-scm.com/docs/git-log#_pretty_formats)

### Log response properties are out of order

The properties of `git.log` are fetched using the character sequence `ò` as a delimiter. If your commit messages
use this sequence, supply a custom `splitter` in the options, for example: `git.log({ splitter: '💻' })`

### Pull / Diff / Merge summary responses don't recognise any files

-  Enable verbose logs with the environment variable `DEBUG=simple-git:task:*,simple-git:output:*`
-  Check the output (for example: `simple-git:output:diff:1 [stdOut] 1 file changed, 1 insertion(+)`)
-  Check the `stdOut` output is the same as you would expect to see when running the command directly in terminal
-  Check the language used in the response is english locale

In some cases `git` will show progress messages or additional detail on error states in the output for
`stdErr` that will help debug your issue, these messages are also included in the verbose log.

### Legacy Node Versions

From `v3.x`, `simple-git` will drop support for `node.js` version 10 or below, to use in a lower version of node will
result in errors such as:

-  `Object.fromEntries is not a function`
-  `Object.entries is not a function`
-  `message.flatMap is not a function`

To resolve these issues, either upgrade to a newer version of node.js or ensure you are using the necessary polyfills
from `core-js` - see [Legacy Node Versions](https://github.com/steveukx/git-js/blob/main/docs/LEGACY_NODE_VERSIONS.md).

# Examples

### using a pathspec to limit the scope of the task

If the `simple-git` api doesn't explicitly limit the scope of the task being run (ie: `git.add()` requires the files to
be added, but `git.status()` will run against the entire repo), add a `pathspec` to the command using trailing options:

```typescript
import { simpleGit, pathspec } from "simple-git";

const git = simpleGit();
const wholeRepoStatus = await git.status();
const subDirStatusUsingOptArray = await git.status([pathspec('sub-dir')]);
const subDirStatusUsingOptObject = await git.status({ 'sub-dir': pathspec('sub-dir') });
```

### async await

```javascript
async function status(workingDir) {
   let statusSummary = null;
   try {
      statusSummary = await simpleGit(workingDir).status();
   } catch (e) {
      // handle the error
   }

   return statusSummary;
}

// using the async function
status(__dirname + '/some-repo').then((status) => console.log(status));
```

### Initialise a git repo if necessary

```javascript
const git = simpleGit(__dirname);

git.checkIsRepo()
   .then((isRepo) => !isRepo && initialiseRepo(git))
   .then(() => git.fetch());

function initialiseRepo(git) {
   return git.init().then(() => git.addRemote('origin', 'https://some.git.repo'));
}
```

### Update repo and get a list of tags

```javascript
simpleGit(__dirname + '/some-repo')
   .pull()
   .tags((err, tags) => console.log('Latest available tag: %s', tags.latest));

// update repo and when there are changes, restart the app
simpleGit().pull((err, update) => {
   if (update && update.summary.changes) {
      require('child_process').exec('npm restart');
   }
});
```

### Starting a new repo

```javascript
simpleGit()
   .init()
   .add('./*')
   .commit('first commit!')
   .addRemote('origin', 'https://github.com/user/repo.git')
   .push('origin', 'master');
```

### push with `-u`

```javascript
simpleGit()
   .add('./*')
   .commit('first commit!')
   .addRemote('origin', 'some-repo-url')
   .push(['-u', 'origin', 'master'], () => console.log('done'));
```

### Piping to the console for long-running tasks

See [progress events](https://github.com/steveukx/git-js/blob/main/docs/PLUGIN-PROGRESS-EVENTS.md) for more details on
logging progress updates.

```javascript
const git = simpleGit({
   progress({ method, stage, progress }) {
      console.log(`git.${method} ${stage} stage ${progress}% complete`);
   },
});
git.checkout('https://github.com/user/repo.git');
```

### Update repo and print messages when there are changes, restart the app

```javascript
// when using a chain
simpleGit()
   .exec(() => console.log('Starting pull...'))
   .pull((err, update) => {
      if (update && update.summary.changes) {
         require('child_process').exec('npm restart');
      }
   })
   .exec(() => console.log('pull done.'));

// when using async and optional chaining
const git = simpleGit();
console.log('Starting pull...');
if ((await git.pull())?.summary.changes) {
   require('child_process').exec('npm restart');
}
console.log('pull done.');
```

### Get a full commits list, and then only between 0.11.0 and 0.12.0 tags

```javascript
console.log(await simpleGit().log());
console.log(await simpleGit().log('0.11.0', '0.12.0'));
```

### Set the local configuration for author, then author for an individual commit

```javascript
simpleGit()
   .addConfig('user.name', 'Some One')
   .addConfig('user.email', 'some@one.com')
   .commit('committed as "Some One"', 'file-one')
   .commit('committed as "Another Person"', 'file-two', {
      '--author': '"Another Person <another@person.com>"',
   });
```

### Get remote repositories

```javascript
simpleGit().listRemote(['--get-url'], (err, data) => {
   if (!err) {
      console.log('Remote url for repository at ' + __dirname + ':');
      console.log(data);
   }
});
```
