Breaking changes
-
Minimal supported Node.js version is now
18.19.0. (834e372) -
When the
encodingoption is'buffer', the output (result.stdout,result.stderr,result.all) is now anUint8Arrayinstead of aBuffer. For more information, see this blog post. (by @younggglcy) (#586)
const {stdout} = await execa('node', ['file.js'], {encoding: 'buffer'});
console.log(stdout); // This is now an Uint8Array
- await execa('node', ['file.js'], {encoding: null});
+ await execa('node', ['file.js'], {encoding: 'buffer'});
- await execa('node', ['file.js'], {encoding: 'utf-8'});
+ await execa('node', ['file.js'], {encoding: 'utf8'});
- await execa('node', ['file.js'], {encoding: 'UTF8'});
+ await execa('node', ['file.js'], {encoding: 'utf8'});
- await execa('node', ['file.js'], {encoding: 'utf-16le'});
+ await execa('node', ['file.js'], {encoding: 'utf16le'});
- await execa('node', ['file.js'], {encoding: 'ucs2'});
+ await execa('node', ['file.js'], {encoding: 'utf16le'});
- await execa('node', ['file.js'], {encoding: 'ucs-2'});
+ await execa('node', ['file.js'], {encoding: 'utf16le'});
- await execa('node', ['file.js'], {encoding: 'binary'});
+ await execa('node', ['file.js'], {encoding: 'latin1'});
- Passing a file path to
subprocess.pipeStdout(),subprocess.pipeStderr()andsubprocess.pipeAll()has been removed. Instead, a{file: './path'}object should be passed to thestdoutorstderroption. (#752)
- await execa('node', ['file.js']).pipeStdout('output.txt');
+ await execa('node', ['file.js'], {stdout: {file: 'output.txt'}});
- await execa('node', ['file.js']).pipeStderr('output.txt');
+ await execa('node', ['file.js'], {stderr: {file: 'output.txt'}});
- await execa('node', ['file.js']).pipeAll('output.txt');
+ await execa('node', ['file.js'], {
+ stdout: {file: 'output.txt'},
+ stderr: {file: 'output.txt'},
+});
- Passing a writable stream to
subprocess.pipeStdout(),subprocess.pipeStderr()andsubprocess.pipeAll()has been removed. Instead, the stream should be passed to thestdoutorstderroption. If the stream does not have a file descriptor,['pipe', stream]should be passed instead. (#752)
- await execa('node', ['file.js']).pipeStdout(stream);
+ await execa('node', ['file.js'], {stdout: ['pipe', stream]});
- await execa('node', ['file.js']).pipeStderr(stream);
+ await execa('node', ['file.js'], {stderr: ['pipe', stream]});
- await execa('node', ['file.js']).pipeAll(stream);
+ await execa('node', ['file.js'], {
+ stdout: ['pipe', stream],
+ stderr: ['pipe', stream],
+});
- The
subprocess.pipeStdout(),subprocess.pipeStderr()andsubprocess.pipeAll()methods have been renamed tosubprocess.pipe(). The command and its arguments can be passed tosubprocess.pipe()directly, without callingexeca()a second time. Thefrompiping option can specify'stdout'(the default value),'stderr'or'all'. (#757)
- await execa('node', ['file.js']).pipeStdout(execa('node', ['other.js']));
+ await execa('node', ['file.js']).pipe('node', ['other.js']);
- await execa('node', ['file.js']).pipeStderr(execa('node', ['other.js']));
+ await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'stderr'});
- await execa('node', ['file.js']).pipeAll(execa('node', ['other.js']));
+ await execa('node', ['file.js']).pipe('node', ['other.js'], {from: 'all'});
- Renamed the
signaloption tocancelSignal. (#880)
- await execa('node', ['file.js'], {signal: abortController.signal});
+ await execa('node', ['file.js'], {cancelSignal: abortController.signal});
- Renamed
error.killedtoerror.isTerminated. (#625)
try {
await execa('node', ['file.js']);
} catch (error) {
- if (error.killed) {
+ if (error.isTerminated) {
// ...
}
}
subprocess.cancel()has been removed. Please use eithersubprocess.kill()or thecancelSignaloption instead. (#711)
- subprocess.cancel();
+ subprocess.kill();
- Renamed the
forceKillAfterTimeoutoption toforceKillAfterDelay. Also, it is now passed toexeca()instead ofsubprocess.kill(). (#714, #723)
- const subprocess = execa('node', ['file.js']);
- subprocess.kill('SIGTERM', {forceKillAfterTimeout: 1000});
+ const subprocess = execa('node', ['file.js'], {forceKillAfterDelay: 1000});
+ subprocess.kill('SIGTERM');
- The
verboseoption is now a string enum instead of a boolean.falsehas been renamed to'none'andtruehas been renamed to'short'. (#884)
- await execa('node', ['file.js'], {verbose: false});
+ await execa('node', ['file.js'], {verbose: 'none'});
- await execa('node', ['file.js'], {verbose: true});
+ await execa('node', ['file.js'], {verbose: 'short'});
- The
execPathoption has been renamed tonodePath. It is now a noop unless thenodeoption istrue. Also, it now works even if thepreferLocaloption isfalse. (#812, #815)
- await execa('node', ['file.js'], {execPath: './path/to/node'});
+ await execa('node', ['file.js'], {nodePath: './path/to/node'});
- The default value for the
serializationoption is now'advanced'instead of'json'. In particular, when callingsubprocess.send(object)with an object that contains functions or symbols, those were previously silently removed. Now this will throw an exception. (#905)
- subprocess.send({example: true, getExample() {}});
+ subprocess.send({example: true});
- If
subprocess.stdout,subprocess.stderrorsubprocess.allis manually piped, the.pipe()call must now happen as soon assubprocessis created. Otherwise, the output at the beginning of the subprocess might be missing. (#658, #747)
const subprocess = execa('node', ['file.js']);
- setTimeout(() => {
subprocess.stdout.pipe(process.stdout);
- }, 0);
- Signals passed to
subprocess.kill()and to thekillSignaloption cannot be lowercase anymore. (#1025)
- const subprocess = execa('node', ['file.js'], {killSignal: 'sigterm'});
+ const subprocess = execa('node', ['file.js'], {killSignal: 'SIGTERM'});
- subprocess.kill('sigterm');
+ subprocess.kill('SIGTERM');
Features
Execution
- Use the template string syntax with any method (including
execa()), as opposed to only$. Conversely,$can now use the regular array syntax. (#933) - A command's template string can span multiple lines. (#843)
- Share options between multiple calls, or set global options, by using
execa(options). (#933, #965) - Pass a file URL (as opposed to a file path string) to
execa(),execaNode(), theinputFileoption, thenodePathoption or theshelloption. (#630, #631, #632, #635)
Text lines
- Split the output into text lines by using the
linesoption. (#741, #929, #931, #948, #951, #957) - Subprocess is now an async iterable, iterating over the output lines while the subprocess is running. (#923)
Piping multiple subprocesses
- Simpler syntax: pass the command directly to
subprocess.pipe()without callingexeca(). A template string can also be used. (#840, #859, #864) - Wait for both subprocesses to complete. Error handling has been improved too. (#757, #778, #834, #854)
- Retrieve the result of each subprocess (not only the last one) by using
result.pipedFromanderror.pipedFrom. (#834) - Pipe 1 or many subprocesses to 1 or many subprocesses. (#834)
- Pipe subprocesses using other file descriptors than
stdin/stdout/stderrby using thefromandtopiping options. (#757, #834, #903, #920) - Cancel piping subprocesses by using the
unpipeSignalpiping option. (#834, #852)
Input/output
- Pass an array with multiple values to the
stdin,stdoutandstderroptions. For example,stdout: ['inherit', 'pipe']prints the output to the terminal while still returning it asresult.stdout. (#643, #765, #941, #954) - Redirect the input/output from/to a file by passing a
{file: './path'}object or a file URL to thestdin,stdoutorstderroption. (#610, #614, #621, #671, #1004) - Transform or filter the input/output by passing a generator function to the
stdin,stdoutorstderroption. (#693, #697, #698, #699, #709, #736, #737, #739, #740, #746, #748, #755, #756, #780, #783, #867, #915, #916, #917, #919, #924, #926, #945, #969) - Provide some binary input by passing an
Uint8Arrayto theinputorstdinoption. (834e372, #670, #1029) - Provide some progressive input by passing a sync/async iterable to the
stdinoption. (#604, #944) - Provide multiple inputs by combining the
stdin,inputandinputFileoptions. (#666) - Return other file descriptors than
result.stdoutandresult.stderrby usingresult.stdio. (#676) - Specify different values for
stdoutandstderrwith the following options:verbose,lines,stripFinalNewline,maxBuffer,buffer. (#966, #970, #971, #972, #973, #974)
Streams
- Redirect the input/output from/to a web stream by passing a
ReadableStreamorWritableStreamto thestdin,stdoutorstderroption. (#615, #619, #645) - Transform or filter the input/output by passing a
Duplex, Node.jsTransformor webTransformStreamto thestdin,stdoutorstderroption. (#937, #938) - Convert the subprocess to a stream by using
subprocess.readable(),subprocess.writable()orsubprocess.duplex(). (#912, #922, #958)
Verbose mode
- Print the subprocess' completion, duration and errors with the
verbose: 'short'orverbose: 'full'option. (#887, #890) - Print the subprocess' output with the
verbose: 'full'option. (#884, #950, #962, #990) - Prettier formatting and colors with the
verboseoption. (#883, #893, #894)
Debugging
- Retrieve the subprocess' duration by using
result.durationMsanderror.durationMs. (#896) - Retrieve the subprocess' current directory by using
result.cwd. Previously onlyerror.cwdwas available. Also,result.cwdanderror.cwdare now normalized to absolute file paths. (#803) - Printing
result.escapedCommandin a terminal is now safe. (#875)
Errors
- The
ExecaErrorandExecaSyncErrorclasses are now exported. (#911) - Find the subprocess failure's root cause by using
error.cause. (#911) - Know whether the subprocess failed due to the
maxBufferoption by usingerror.isMaxBuffer. (#963) - Improved
error.message:error.stdoutanderror.stderrare now interleaved if thealloption istrue. Additional file descriptors are now printed too. Also, the formatting has been improved. (#676, #705, #991, #992) - Control characters in
error.messageare now escaped, so they don't result in visual bugs when printed in a terminal. (#879) - Improved stack trace when an
errorevent is emitted onsubprocess.stdoutorsubprocess.stderr. (#814)
Termination
- Specify an error message or stack trace when terminating a subprocess by passing an error instance to
subprocess.kill(). (#811, #836, #1023) - The
forceKillAfterDelayandkillSignaloptions now apply to terminations due not only tosubprocess.kill()but also to thecancelSignal,timeout,maxBufferandcleanupoptions. (#714, #728)
Node.js files
- Use the
nodePathandnodeOptionsoptions with any method, as opposed to onlyexecaNode(), by passing thenode: trueoption. (#804, #812, #815) - When using
execaNode()or thenode: trueoption, the current Node.js version is now inherited deeply. If the subprocess spawns other subprocesses, they will all use the same Node.js version. (#812, #815, #1011)
Synchronous execution
- Use the
allandbuffer: falseoptions withexecaSync(), as opposed to onlyexeca(). (#953, #956) - Added the
$.salias for$.sync. (#594)
Inter-process communication
- Use the
ipc: trueoption, as opposed to the more verbosestdio: ['pipe', 'pipe', 'pipe', 'ipc']option. (#794)
Input validation
- Improved the validation of the
input,timeout,cwd,detached,cancelSignalandencodingoptions. (#668, #715, #803, #928, #940) - Improved the validation of the arguments passed to
execa()and the other exported methods. (#838, #873, #899) - Improved the validation of signals passed to
subprocess.kill()and to thekillSignaloption. (#1025)
Bug fixes
- Fixed passing
undefinedvalues as options. This now uses the option's default value. (#712) - Fixed the process crashing when the
inputFileoption points to a missing file. (#609) - Fixed the process crashing when the
bufferoption isfalseandsubprocess.stdouterrors. (#729) - Fixed the process crashing when passing
'overlapped'to thestdoutorstderroption withexecaSync(). (#949) - Fixed the process crashing when multiple
'error'events are emitted on the subprocess. (#790) - Fixed the
reject: falseoption not being used when the subprocess fails to spawn. (#734) - Fixed some inaccuracies with
error.isTerminated. (#625, #719)- It is now
truewhen the subprocess fails due to thetimeoutoption. - It is now
truewhen callingprocess.kill(subprocess.pid), except on Windows. - It is now
falsewhen using non-terminating signals such assubprocess.kill(0).
- It is now
- Fixed missing
error.signalanderror.signalDescriptionwhen the subprocess is terminated by thecancelSignaloption. (#724) - Fixed a situation where the error returned by an
execa()call might be modified by anotherexeca()call. (#796, #806, #911) - Fixed the
verboseoption printing the command in the wrong order. (#600) - Fixed using both the
maxBufferandencodingoptions. For example, when usingencoding: 'hex',maxBufferwill now be measured in hexadecimal characters. Also,error.stdout,error.stderranderror.allwere previously not applying themaxBufferoption. (#652, #696) - Fixed the
maxBufferoption not truncatingresult.stdoutandresult.stderrwhen usingexecaSync(). (#960) - Fixed empty output when using the
buffer: trueoption (its default value) and iterating oversubprocess.stdoutorsubprocess.stderr. (#908) - Fixed
subprocess.allstream incorrectly being in object mode. (#717) - Ensured
subprocess.stdoutandsubprocess.stderrare properly flushed when the subprocess fails. (#647) - Fixed a race condition leading to random behavior with the
timeoutoption. (#727)
