Tsumuri — Mon, 19 Sep 2022 05:32:10 +0000

WebSockets are occasionally accessed illegally.
I want to prevent that.
I'm thinking of an authentication method.
Please let me know if there is a better way.

Push.js's Help

Tsumuri — Sat, 02 Jul 2022 01:59:21 +0000

Using Push.js of the web js library,
When notifying many times,
I want to automatically turn off the notification when the next notification comes.
Is there a way?

I would like to know how to specify other than the number of milli seconds.

Please help...

I'm going to use it for chat notifications when another tab is open.

Is it a DDos attack?
How long should I wait?

I want to convert an HTML file in express...

First of all, I want you to see there.

index.js quote

webdata = (fs.readFileSync(__dirname + '/web/wiki.html', 'utf8'));
webdata=String(webdata)
webdata = webdata.replace('{tmp.data.name}',articlesname);
 res.end(webdata);

web/wiki.html

<!DOCTYPE HTML>
<html>
<head>
...
</head>
    <body>
      <h2>${tmp.data.name}</h2>
      <hr>
      <br>
      <div id="article">
          ：
          ：
    </body>
</html>

Next, I will explain what I want to do.

I want to use replace to read the string "$ {tmp.data.name}" in HTML and use Node.js Express to make it the content of a variable.

However,

webdata=String(webdata)
webdata = webdata.replace('{tmp.data.name}',articlesname);

does not work.
Variables are defined.
Also, I couldn't try it with a string instead of a variable.
Please help me...

The project you created with replit is taking a long time to respond. Is this just me?

The response time of the website published
by replit is taking too long.
Is this a temporary issue?
Or is there a solution?

Workaround of [object Object]

Tsumuri — Sat, 26 Mar 2022 23:01:49 +0000

When JavaScript handles an object such as json andthe result is output,

[object Object]

maybe displayed.
This is because we are trying to output the data in object format as it is.
This can be solved by converting the number to a string.

//json_object => [object Object] Error Workaround
JSON.stringify(json_object);

and solve it.
I look forward to helping you.
