定义了如下类型，但是 WebStorm Code Complete 无法正确提示类型，只有加上 export 才能正确处理。
1// should export
2// otherwise, it will not take effect
3export declare global {
4 namespace PrismaJson {
5 type Tags = string[];
6 type Size = {
7 width: number;
8 height: number;
9 };
10 }
11}@typescript-eslint/no-use-before-define settings1/* eslint @typescript-eslint/no-use-before-define: ["error", { "functions": false }] */
2func();
3function func(){
4 console.log('hello world');
5}好用的插件，https://react-buddy.com/

nodejs 如何执行 shell 命令，并把结果实时回显输出？
1const exec = require('child_process').exec;
2
3exec('shell 命令', (error, stdout, stderr) => {
4 console.log({ error, stdout, stderr });
5});我尝试如上写法，但是发现回调函数 (error, stdout, stderr)=>{} 在命令执行完毕才一次性返回， 而不是实时回显
请问如何让输出实时回显？
你需要用 spawn, 它是一个事件触发器对象版本的 exec, 以下例子来自 node 官方文档:
https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options
1const { spawn } = require('child_process');
2const ls = spawn('ls', ['-lh', '/usr']);
3
4ls.stdout.on('data', (data) => {
5 console.log(`stdout: ${data}`);
6});
7
8ls.stderr.on('data', (data) => {
9 console.error(`stderr: ${data}`);
10});
11
12ls.on('close', (code) => {
13 console.log(`child process exited with code ${code}`);
14});1Error: spawn ENOENT
2 at errnoException (child_process.js:1000:11)
3 at Process.ChildProcess._handle.onexit (child_process.js:791:34)simply adding shell: true option solved my problem:
incorrect:
1const { spawn } = require('child_process');
2const child = spawn('dir');correct:
1const { spawn } = require('child_process');
2const child = spawn('dir', [], {shell: true});based on Node.js Documentation (thank to @Boris comment):
Note that:
if the shell option is enabled, do not pass unsanitized user input to this function. Any input containing shell metacharacters may be used to trigger arbitrary command execution.
One more note: If you experience UI freezes while using tag completion, as a workaround, you can try to disable "Preferences | Editor | General | Smart Keys | HTML/CSS" -> "Insert required attributes on tag completion" (and may be other similar options in the settings). I am not sure that this will fix the problem completely, but at least it should reduce the freezes.
