I'm going to use certbot based on nestjs. So I want to set up nestjs to read the txt file under /.well-known/acme-challenge/. However, I don't know how to set it up to read the txt file under that path. If you use the ServerStaticModule, it keeps loading index.html. Could you tell me how to set it up?
--my nestjs app.module.ts--
--Result--
result is importing /.well-known/acme-challeng/index.html. I want to bring file.txt. What should I do?

Is there any way to parse data to a .yaml file in node.js? I've been searching about this for hours and found nothing useful.
Let's say I have a string in a .yaml file:
message: Hello, ${user.fullName}, have a nice day.
As I've been reading, there's something called "placeholders" but it seems only available in spring framework.
This is what I found.
And in other places, they use a different syntax like {{user.fullName}}
So, is there any way to replace ${user.fullName} with an actual value in node.js? I don't know if I should manually handle this thing that they call "placeholder" myself with string.replace(). I checked the main YAML docs and there's nothing called "placeholder" or even "variable" in their entire docs!
But, similarly, I can achieve a similar result with pug.js using #{user.fullName} (with # instead) and then call something like: pug.renderFile('template.pug', {fullName: 'Timothy'}). Check pug.js docs for more details.
Thanks for your help!
I am having issues attempting to properly use pkg (nodejs module) properly.
I am doing a stand alone file manager (well, it would swap video/audio files to & from preselected directories, intended to allow it without any internet connection it self to remove & add files to a syncing folder like onedrive/dropbox/googledrive/etc. using a text file.)
The issue I am having, is I am at a loss of after I package it into a binary.. I do not understand how to allow/force it to create/read the text file outside compiled binary.
-- I would love for it to be within the same folder as the executable.
I am attempting to find a way to store data without having to share the sourcecode, or require node be installed on other machines.
-- I intend to have a minimal permissions as possible, and outside reading/writing the config & 'database' [which is simply a text file with what files are in the local storage, and what files are & are not in the remote storage]
What am I missing about pkg, & if it can store data internally some how... how do I get it to read an external file?
-- Though I would greatly prefer to have the txt files outside the binary & in plain text easy to read.
As a side question, I am not understanding how to pass an argument through & use it inside the program after it's compiled. [Hell, I'm having a heck of a time, properly understanding the readme for the pkg module]
Use fs features to load config object as in this three-lines of code
filename="./config.json";
let rawdata = fs.readFileSync(filename);
let config = JSON.parse(rawdata);
config.json must be in same direcory of pkg executable
If you need to change path of config.json, you will able to specify full-path of this file using command line arguments.
These can be read at runtime using process.argv variable as explained here
I have a check.env file, in which I have some variables like
SharedAccessKey=
I want to put a value in the check.env file from my node.js code. Articles on internet are there for updating at the running time of node.js, but my requirement is to change in the file and keep the file with changes made.
How can I accomplish that.
I got this link : How to change variables in the .env file dynamically in Laravel?
but it is in some other language, how can I do in node.js.
I was unable to find out the best solution so went with another solution of mine that I took.
I am using two files now both .env extensions and I am copying main .env file to another empty .env file (like check1.env to check2.env).
Any modifications I am making is in the second file (check2.env).
And I am using string replacement in the .env file, using fs.readLine() and getting the string and the data.replace(), this worked for me.
The reason to use two .env files is that even if I change in the second file, again by copying from the first file I will get same string search and will replace with a different value.
-- Please suggest if there is an any better approach. Thanks
I'm creating a NodeJS service with serverless framework to validate a feed so I added a schema file (.json) to the service but I can’t make it work.
It seems to not be included in the package. Lambda doesn't find that file.
First I just run sls package and check the zip contents but the file is not present.
I also tried to include the file with:
package:
include:
- libs/schemas/schema.json
but still not works.
How can I make sure a static file is included in the package and can be read inside the lambda function?
It depends on how you are actually trying to load the file.
Are you loading it with fs.readFile or fs.readFileSync?
In that case, Serverless doesn't know that you're going to need it. If you add a hint for Serverless to include that file in the bundle then make sure that you know where it is relative to your current working directory or your __dirname.
Are you loading it with require()? (Do you know that you can use require() to load JSON files?) In that case, Serverless should know that you need it, but you still need to make sure that you got the path right.
If all else fails then you can always use a dirty hack.
For example if you have a file 'x.json' that contains:
{
"a": 1,
"b": 2
}
then you can change it to an x.js file that contains:
module.exports = {
"a": 1,
"b": 2
};
that you can load just like any other .js file, but it's a hack.
From what I've found you can do this in many ways:
As it is stated in another answer: if you are using webpack you need to use a webpack plugin to include files in the lambda zip file
If you are not using webpack, you can use serverless package commnad (include/exclude).
You can create a layer and reference it from the lambda (the file will be in /opt/<layer_name>. Take in consideration that as today (Nov20) I haven't found a way of doing this if you are using serverless.ts without publishing the layer first (lambda's layer property is an ARN string and requires the layer version).
If your worried about security you can use AWS Secrets as it is stated in this answer.
You can do what #rsp says and include it in your code.
For those struggling to find a solution in 2022: use package.patterns parameter. Example:
package:
patterns:
- libs/schemas/schema.json
- !libs/schemas/schema-prod.json
(! in front of the file path excludes specified pattern)

I wonder if you can configure logstash in the following way:
Background Info:
Every day I get a xml file pushed to my server, which should be parsed.
To indicate a complete file transfer afterwards I get an empty .ctl (custom file) transfered to the same folder.
The files both have the following name schema 'feedback_{year}{yearday}_UTC{hoursminutesseconds}_51.{extention}' (e.g. feedback_16002_UTC235953_51.xml). So they have the same file name but one is with .xml and the other is a .ctl file.
Question:
Is there a way to configure logstash to wait parsing the xml file until the according .ctl file is present?
EDIT:
Is there maybe a way to archiev that with filebeat?
EDIT2:
It would also be enough to be able to configure logstash in a way that it will wait x minutes before starting to process a new file, if that is easier.
Thanks for any help in advance
Your problem is that you don't want to start the parser before the file transfer hasn't been completed. So, why don't push the data to a file (file-complete.xml) when you find your flag file (empty.ctl)?
Here is the possible logic for a script and runs using crontab:
if empty.ctl exists:
Clear file-complete.xml
Add the content of file.xml to file-complete.xml.
Remove empty.ctl
This way, you'd need to parse the data from file-complete.xml. I think is simpler to debug and configure.
Hope it helps,
