需要通过我现有的package.json增加Node max_old_space_size

Question

我继承的应用程序已经开始变大，并且我收到错误消息CALL_AND_RETRY_LAST分配失败-JavaScript堆内存不足。根据我的研究，我需要设置节点参数max_old_space_size。

我当前正在运行Node 7.8.0，因此它似乎没有出现，我可以使用环境变量NODE_OPTIONS，但我尝试将其设置为没有问题。我已经在下面粘贴了现有的package.json文件，但是我无法弄清楚在脚本部分中可以在何处放置参数-max_old_space_size = 2048

当内存达到1.6 GB时，节点进程通常会因上述错误而崩溃

有一个npm软件包。 :)https://www.npmjs.com/package/increase-memory-limit#running-from-npm-task

Answer 2

这就是我的使用方式：

"scripts": {
  "high-memory": "node --max_old_space_size=2048 ./node_modules/.bin/ts-node",
  "generate:client": "npm run high-memory -- ./swagger/generate-client.ts --baseApiUrl=http://localhost:5003",
  "generate:client:prod": "npm run high-memory -- ./swagger/generate-client.ts --baseApiUrl=%API_URL%",
}
