3Speak Mobile App Development Update by Sagar - Setting Up Acela Core, Solving Errors, and more

Hello @threespeak Community Members & Hive Community Members,

With this post, I'll share the development updates & items on which I (@sagarkothari88) was working. Accidentally, OBS decided to pick a different audio device & due to which no audio was captured. You can find updates as follows.

Setting Up Acela-core

• Acela-Core is a new backend core for decentralized video applications on HIVE.
• It supports both off-chain & on-chain data.
• I (@sagarkothari88) checked it out locally & resolved all the issues he faced.

Setting up .env & resolving related issues

• To run, you need some of the configs.
• After coordinating with the team, I got the necessary env variables.
• Even after that, I faced some errors due to missing env variables.
• After turning off cluster-related services, I was able to move forward.

TUSd uploader

• At first, I was unaware & I was running the TUSd instance independently.
• After knowing there was a script already for it, I closed that instance & ran on my own.
• https://github.com/spknetwork/acela-core/blob/main/runTusd.sh
• With that, I had running the TUSd uploader locally

TUSd Hooks

• Even after running it, It kept throwing errors.
• I created a data folder locally & updated runTusd.sh as follows.
• It resolved TUSd issues.
• As you can see here, I changed upload-dir from /data to ./data

tusd -upload-dir=./data/ \
     -base-path="/files" \
     -host="127.0.0.1" \
     -port="1080" \
     -behind-proxy \
     --hooks-enabled-events pre-create,post-create,post-finish,post-finish,post-terminate,post-receive \
     -max-size 5000000000 \
     -hooks-http http://localhost:4569/api/v1/upload/tus-callback

Other errors

• I also encountered IPFS Cluster issues.
• Those I managed to resolve by coordinating with the teI also encountered some compilation errors & got them fixed locally.
• After all of these, I was all set.

Learning NestJS

• Acela core is written using the NestJS Framework.
• It's been over a year & I have not learned about NestJS.
• I found a playlist on YouTube to learn NestJS.
• I completed approximately 18 videos from that playlist.
• After 18 videos, I started contributing to the Acela-core project.

Acela-Core - Posting Authority before logging in

• https://github.com/spknetwork/acela-core/pull/8/files.
• Granting JWT Token only if posting authority is found.
• This JWT Token will be used for upvotes, comments, and posts.
• Without posting authority, all of the operations may fail.
• So, it's best to check at the time of login /login_singleton
• It would be the front-end's responsibility to get posting authority first.
• After that front-ends can generate proof & proof of payload & - execute/login_singleton for logging in.

Acela-Core - Max 5 GB Upload

• We need to ensure that file size is no bigger than 5 GB.
• https://github.com/spknetwork/acela-core/pull/9.
• In src/services/uploader/uploading.service.ts, I added an extra check & it then shows an error if the file size is too big.

New FrontEnd - Video Format

• This will be the third check we'll add to the upload process.
• It makes sure that users are uploading videos in the right format.
• With this, we wish to improve the upload experience.
• This work is in progress.

Exchanging GQL queries

• Juneroy & I exchanged several GraphQL queries.
• With this, he could implement it on New 3Speak FrontEnd.
• Shared Queries for the following:
  • Subscribed feed
  • Trending feed
  • New feed
  • First upload
  • Community Feed
  • Tags Feed

What are the next tasks?

• Acela-Core - Fix Upvote API.
• Acela-Core - create-upload API failing.
• 3Speak Legacy Studio - Add posting authority using Active Key, which is not working.
• 3Speak Legacy Studio - Connect the account using Active Key, which is not working.
• 3Speak Legacy FrontEnd - 3Speak Twitter handle.
• 3Speak Legacy FrontEnd - Update Twitter Icon.
• New tasks will be assigned based on daily stand-ups.
