Portable versions of explorer?

[username1565]

I try to install your explorer https://github.com/wavesplatform/WavesExplorerLite
but I see some error after trying to start command

yarn install

after this try to run

node-sass

Here is the partial log:

yarn install v1.17.3
[1/4] Resolving packages...
[2/4] Fetching packages...
info fsevents@1.2.9: The platform "win32" is incompatible with this module.

Excluding it from installation.

...

then I see this errors.

This need Python27 in folder C:\\Python27\\python.EXE.
I just try the command

npm install --global windows-build-tools

And I see Python27 folder then,
but yarn install cann't compile and stop with errors after node-sass - step.

UPD: Trying this again with administrative privelegies - stop after python27 found...
Then, try:

npm rebuild node-sass

And got fail... Errors...

I see some files was been added in /node_modules/ folder.
And I see too many errors, while i try to do compilation of this.

---

Also, I tried to install this old block-explorer: https://github.com/wavesplatform/WavesExplorerLite/tree/old-explorer
But this don't working too. Some variable is undefined there, inside fs.js.

Do you have portable versions of this explorers, in zip-archive, without need to any installation?
Maybe you can add node.js portable and python portable, there, inside zip, no?

[beregovoy68]

Hi

I've never tried to build Explorer on Windows. I don't see any error messages in console logs that you provided. Could you specify what errors do you see?

To be able to help, I need to understand what you're going to do. Please describe your use case in more detail.

If you just need to run Explorer locally, you can use this docker image https://hub.docker.com/r/wavesplatform/explorer

Cheers

[username1565]

Hi, @beregovoy68!

There is some errors with node.js, and module node-sass...
This is the problem on my side because the command

npm install --global windows-build-tools

cann't be finished,
and the command

npm rebuild node-sass

cann't be finished too.
This node-sass is runned after run yarn start, and I see this commands in your docker image.
So I don't think this image can help me, really.

But, I see this required python27.EXE,
and maybe you didn't write
some additional dependencies in the guide for building.

Also, i think, will be better to you just make a full package, including python and node.js,
without any dependencies, and make this explorer - portable.
Or just sharing the already compiled and builded cross-platform version.

Hi, @username1565! What the version of node u use?
Check support of your version nodejs here.

[username1565]

Hi, @tsigel. Thanks for your info!

I see, my node version is:

>node -v
v12.3.1

There, by your link, I see:

NodeJS Node 12 | node-sass 4.12+

So I just did update node-sass:

>WavesExplorerLite-master>npm install -global node-sass
...
Testing binary
Binary is fine
+ node-sass@4.12.0
updated 1 package in 7.196s

Then, just

>yarn install
yarn install v1.17.3
...

And after slow process of linking 40966 dependendies...
this sucessfully finished:

yarn install v1.17.3
warning package-lock.json found. Your project contains lock files generated by t
ools other than Yarn. It is advised not to mix package managers in order to avoi
d resolution inconsistencies caused by unsynchronized lock files. To clear this

Try to build old wavesblockexplorer from this branch, in another folder...

>cd folder_path_for_unpacked old wavesblockexplorer...
>npm install -g gulp-cli
+ gulp-cli@2.2.0
updated 1 package in 14.29s

Try to install block-explorer:

Then I did try to install gulp-cli in old wavesblockexplorer folder:

the same errors...

I see from this logs, npm version is deprecated, so I did try update npm

All pathways, seems like correct, but error after try to take something from git.
That means, maybe something need to change on your side.
And maybe this info for current wavesexplorer - not for THIS OLD http://wavesblockexplorer.com/

[beregovoy68]

Hi @username1565,

If you want to build an old Explorer, you also need to install bower.
npm install -g bower - to install bower globally
npm install - to install Explorer dependencies
gulp build - to build testnet version of old explorer

Please give it a try and let me know if it worked or not.

[username1565]

Hi, @beregovoy68!

Try to install bower:

>npm install -g bower
npm WARN deprecated bower@1.8.8: We don't recommend using Bower for new projects

[username1565]

I just did try to find in google this error:

But, here, in your guide, I see old block-explorer can be runned locally, without building:

Run locally
npm install
node server.js
Open http://localhost:3000 in browser. You'll see testnet version of explorer.

Then I did try to do it:

After read this error carefully, I see some files does not exists in /build folder,
so I just did rename /src-folder to /build-folder, and try to start it again.
I see server is listening the port 3000:

G:\coins\WAVES_FULL_NODE\NEW_NODE\WavesExplorerLite-old-explorer>node server.js
Server listening on port 3000

Go to http://localhost:3000/ and see this:

...
Ctrl+C
...
Exit...

Don't know what to do now...

Maybe, you need to change the folder name from src to build, in your repositary,
or just pathway to this folder in some file, no?
Also, maybe, you need to fix something to correct working this explorer, like here: https://wavesblockexplorer.com/
not like on my screen.
And also, maybe, there is possible to install this, using already installed yarn?

[username1565]

I just did try to build this, using pre-installed yarn, using yarn install:

When I tried to open http://localhost:3000/ I saw previous posted screen,
and I don't see working old block-explorer like this: https://wavesblockexplorer.com/
But sometimes, I saw this picture when I did try to visit https://wavesblockexplorer.com/,
and this picture was been showed only short time, then redirect to working block-explorer, or updating this info by loading html-elements...
But in my case, I don't see working block-explorer... Maybe because I did rename /src folder to /build-folder... WTF? What should I do? ЧЯДНТ?

[username1565]

I just got success for compile current and old waves-explorers.

Earlier, I did already try to do npm rebuild node-sass,
and before this I did npm install node-sass
and node-sass (plus node-gyp together with this) was been installed, locally, in the folder node_modules.
But after that success compilation, and after removing that folder, new compilation was been failed, and global installed node-sass run the PowerShell, with some errors from the module gyp.
So I did compile new wavesexplorer again,
with the following consecutive actions:

Win+R -> cmd.exe
>G:
>cd G:\coins\WAVES_FULL_NODE\NEW_NODE\WavesExplorerLite-master\WavesExplorerLite-master
>yarn add node-sass
...(linking 42245 dependencies)
>yarn install
...very fast done.
>yarn start
...see working wavesexplorer.

As you can see, node-sass was been added not globally, and here is not using gulp.
Moreover, before this, I did remove gulp and node-sass globally:

G:\coins\WAVES_FULL_NODE\NEW_NODE>yarn global remove gulp-cli
yarn global v1.17.3
[1/2] Removing module gulp-cli...
[2/2] Regenerating lockfile and installing missing dependencies...
success Uninstalled packages.
Done in 9.26s.

G:\coins\WAVES_FULL_NODE\NEW_NODE>yarn global remove node-sass
yarn global v1.17.3
[1/2] Removing module node-sass...
[2/2] Regenerating lockfile and installing missing dependencies...
success Uninstalled packages.
Done in 1.40s.

And then, I didn't saw switching cmd to PowerShell, after yarn install starting this locally-installed node-sass.
Also, the command yarn add node-sass working before (sic!) yarn add gulp-cli (not global),
and you can add this command - in Readme.md.

I still cann't using gulp for test your published commands, because there is some errors, and I don't know correct version to install. What version did you use, can you tell?

The old wavesblockexplorer was been compiled after some edits and modifications...
Earlier, I saw on http://localhost:3000/ the result, as there is on the picure, here.
So I just did go to https://wavesblockexplorer.com/ and see source code of this page.
I see in src/index.html there is some empty injections in two different places.
After fill this correctly, and add the scrypts and styles, this block-explorer may be working and opening good.

One more fix was been at line 11 I just did change the directory:
change from '/build' to '/src' in server.js

var basedir = __dirname + '/src';

Then...

Win+R -> cmd.exe
G:
cd G:\coins\WAVES_FULL_NODE\NEW_NODE\WavesExplorerLite-old-explorer\WavesExplorerLite-old-explorer
yarn install
...many links...
...done
yarn start
...done. listening port and opening...

I'm not sure, my compiled old block-explorer is working with node directly, because through that scripts, it can loading some info from wavesblockexplorer.com.
But this is working.
So you can test, and fix this code yourself.
Maybe, you can make another repositary (not archive-branch),
and then, perhaps this block-explorer, which normally WORKING IN OLD BROWSERS, it will be developed by community, in the future.

Anyway, right now, you can add the missing files and correct pathways, for correct compilation and working of this.

Best Regards.

UPD:
Yes, I see in this config, there is specified another node: https://waves.guarda.co
and this is specified in two places.
I see Swagger there, and there is hosted the Node REST API.
So this links can be changed to http://127.0.0.1:6869, where the Node REST API is hoste locally, and then old wavesblockexplorer is working, even in LAN, when the Internet is disconnected. I see GET requests in the console of the runned node.

Also, I did try to connect compiled wavesexplorer to my local node, but I have no success. Failed to load blockchain data.
Hm... Maybe need to change something else,
but I saw GET requests in the console of runned node too.

[username1565]

Bump! Need to add some files in the source code to make old blockexplorer working, after installation.

[username1565]

How to disable CORS for wavesexploerlite? After building, this not working, and there is some errors in console, about CORS not allowed on the server.

[beregovoy68]

Could you specify which headers you see in responses from a Waves public node? In particular, what values you get in header access-control-allow-origin?

[username1565]

When I try to open https://wavesexplorer.com/ I just see

Failed to load blockchain data.

I see on the network-tab an XHR-queries to the following URL of yandes:

The same problem, on localhost, after installation of wavesexplorer.

But! This wavesblockexplorer working good: http://wavesblockexplorer.com/
and opening without any problems in both browsers.

All that means need to fix something in the source code, to install this and working without any bugs, like old-wavesexplorer working good, after installation.

[beregovoy68]

I can't see headers for any requests your browser makes to nodes.wavesnodes.com, that's why I can't say what the issue is.

Could you post here your Firefox ESR version?

Anyway, I've reported that back to node support team, they are looking into it. If you still see these errors please contact support@wavesplatform.com.
