You can just delete the node_module directory

<pre><code>rm -rf node_modules/
</code></pre>

There is actually special command for this job
<pre><code>npm ci
</code></pre>
It will delete <code>node_modules</code> directory and will install packages with respect your <code>package-lock.json</code> file

Try 
<a href="https://github.com/voidcosmos/npkill" rel="noreferrer">https://github.com/voidcosmos/npkill</a>

<pre><code>npx npkill
</code></pre>

it will find all node_modules and let you remove them.

You can take advantage of the 'npm cache' command which downloads the package tarball and unpacks it into the npm cache directory.

The source can then be copied in.

Using ideas gleaned from <a href="https://groups.google.com/forum/?fromgroups=#!topic/npm-/mwLuZZkHkfU" rel="noreferrer">https://groups.google.com/forum/?fromgroups=#!topic/npm-/mwLuZZkHkfU</a> I came up with the following node script. No warranties, YMMV, etcetera.

<pre><code>var fs = require('fs'),
path = require('path'),
exec = require('child_process').exec,
util = require('util');

var packageFileName = 'package.json';
var modulesDirName = 'node_modules';
var cacheDirectory = process.cwd();
var npmCacheAddMask = 'npm cache add %s@%s; echo %s';
var sourceDirMask = '%s/%s/%s/package';
var targetDirMask = '%s/node_modules/%s';

function deleteFolder(folder) {
 if (fs.existsSync(folder)) {
 var files = fs.readdirSync(folder);
 files.forEach(function(file) {
 file = folder + "/" + file;
 if (fs.lstatSync(file).isDirectory()) {
 deleteFolder(file);
 } else {
 fs.unlinkSync(file);
 }
 });
 fs.rmdirSync(folder);
 }
}

function downloadSource(folder) {
 var packageFile = path.join(folder, packageFileName);
 if (fs.existsSync(packageFile)) {
 var data = fs.readFileSync(packageFile);
 var package = JSON.parse(data);

 function getVersion(data) {
 var version = data.match(/-([^-]+)\.tgz/);
 return version[1];
 }

 var callback = function(error, stdout, stderr) {
 var dependency = stdout.trim();
 var version = getVersion(stderr);
 var sourceDir = util.format(sourceDirMask, cacheDirectory, dependency, version);
 var targetDir = util.format(targetDirMask, folder, dependency);
 var modulesDir = folder + '/' + modulesDirName;

 if (!fs.existsSync(modulesDir)) {
 fs.mkdirSync(modulesDir);
 }

 fs.renameSync(sourceDir, targetDir);
 deleteFolder(cacheDirectory + '/' + dependency);
 downloadSource(targetDir);
 };

 for (dependency in package.dependencies) {
 var version = package.dependencies[dependency];
 exec(util.format(npmCacheAddMask, dependency, version, dependency), callback);
 }
 }
}

if (!fs.existsSync(path.join(process.cwd(), packageFileName))) {
 console.log(util.format("Unable to find file '%s'.", packageFileName));
 process.exit();
}

deleteFolder(path.join(process.cwd(), modulesDirName));
process.env.npm_config_cache = cacheDirectory;
downloadSource(process.cwd());

I have added few lines inside package.json:

<pre><code>"scripts": {
 ...
 "clean": "rmdir /s /q node_modules",
 "reinstall": "npm run clean &amp;&amp; npm install",
 "rebuild": "npm run clean &amp;&amp; npm install &amp;&amp; rmdir /s /q dist &amp;&amp; npm run build --prod",
 ...
}
</code></pre>

If you want to <code>clean</code> only you can use this <code>rimraf node_modules</code>.

Is there a way to get npm to unbuild all the modules under node_modules? Something like npm rebuild that removes all build artifacts but doesn't rebuild them?

NPM clean modules

JSON

有没有办法让npm卸载node_modules下的所有模块？像npm rebuild这样的东西可以移除所有的构建工件，但不会重建它们？
