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](https://www.youtube.com/playlist?list=PLqLR2H326bY6eRNOXJxWQkvKNlzmJQfLj). - 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.  ## Feedback / Info - Do you want more Info?
