node内存配置（--max-old-space-size）

比较复杂的项目中，angular2编译的时候对CPU和内存需求都会变大。项目中，使用angular-cli@beta28-3编译。需要内存2-3G。node本身，或者说v8本身有一个默认配置:Currently, by default v8 has a memory limit of 512mb on 32-bit systems, and 1gb on 64-bit systems. The limit can be raised by setting --max-old-space-size to a maximum of ~1gb (32-bit) and ~1.7gb (64-bit), but it is recommended that you split your single process into several workers if you are hitting memory limits.
所以我们需要配置一下运行内存。

I’m on OS X EICapitan(10.11.6) and am running node v6.9.1.My machine has 8GB of RAM.

windows很容易就设置:

cd C:\Users\Administrator\AppData\Roaming\npm

修改ng.cmd,追加–max_old_space_size=4096 避免aot时内存溢出

#!/bin/sh
basedir=$(dirname "$(echo "$0" | sed -e 's,\\,/,g')")

case `uname` in
    *CYGWIN*) basedir=`cygpath -w "$basedir"`;;
esac

if [ -x "$basedir/node" ]; then
  "$basedir/node --max-old-space-size=6096 "  "$basedir/../angular-cli/bin/ng" "$@"
  ret=$?
else 
  node --max-old-space-size=6096 "$basedir/../angular-cli/bin/ng" "$@"
  ret=$?
fi
exit $ret

Mac设置：

路径：/Users/free/Documents/angular-cli/caibian-ng/caibian-static/node_modules/.bin

文件：ng

#!/usr/bin/env node --max-old-space-size=4096
'use strict';

// Provide a title to the process in `ps`
process.title = 'angular-cli';

require('../lib/bootstrap-local');
require('../packages/angular-cli/bin/ng');
