For testing purposes, I would like to make it possible to spawn a Node.js console that reads commands from STDIN but before runs a bootstrap script to initialize several variables in the local scope.
出于测试目的,我希望能够生成一个Node.js控制台,该控制台从STDIN读取命令,但在运行引导脚本以初始化本地范围内的多个变量之前。
Does node provide a specific option for this?
节点是否为此提供了特定选项?
I tried to do the trick with the following bash script, but unfortunately, it outputs nothing:
我尝试使用以下bash脚本来完成这个技巧,但遗憾的是,它没有输出任何内容:
{ cat bootstrap.js; cat; } | node

As it turned out, the script quoted in the question is only missing the node option -i that causes node to
事实证明,问题中引用的脚本只缺少导致节点的节点选项-i
always enter the REPL even if stdin does not appear to be a terminal
即使stdin似乎不是终端,也总是输入REPL
As a consequence, this does the trick:
因此,这就是诀窍:
cat bootstrap.js - | node -i
The behavior is still not optimal though as STDIN is printed twice.
尽管STDIN打印两次,但行为仍然不是最佳的。
See https://*.com/a/23037234/449012 for another solution that behaves just like the default console.
