# Streamline DevEx: Mobile, Rust and Web dev

**Estimated date of completion**: {Enter date} TODO

**Resources Required for 2025H2**:
- {roles and % application to it}
- {external services consumed (Vac/IFT)}
- {infrastructure}

Complete the Waku API implementation in nwaku by implementing edge node mode (Status' Light Mode).

Streamline the Developer Experience by delivering a Rust SDK that implements the full Waku API and is available on crates.io.
As well as building an easy-to-use local dev environment from the browser, enabling developers to build web apps without
relying on external connectivity; as well as opting in and out of RLN, and include a local RLN dev environment.

Finalize the integration of nwaku in Status application by setting up nwaku-based build for Mobile platforms.

## Risks

| Risk                    | (Accept, Own, Mitigation)                                                                                                                                                |
|-------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| nwaku performance       | Performance of nwaku in comparison to go-waku will be measured by DST during H2 and may raise issues that will become blockers for pratical usage of nwaku in Mobile.    |
| Publishing to crates.io | One of the challenge to publish libwaku on crates.io is the package size. Several strategy may be developed and tried to find a way to distribute Nim-based Rust crates. |
| Local dev harness       | Creating a local dev environment may be a challenge due to the nature of Waku and RLN, as we would need to locally coordinate bootstrap and blockchain emulation.        |

### Local Web Dev Harness

TODO: update milestone
1 js-waku engineer, 70% cap allocated;
start 1st Sep, end 19th Sep;


**Owner**: js-waku

**Feature**: [Local Web Dev Harness](/FURPS/application/local_web_dev_harness.md)

**FURPS**:

- F1. Runs local Waku node to test Web application without relying on external connectivity.
- F2. js-waku runs in NodeJS for testing and CI purposes.

- U1. Developer only need to run a script or preset to start local Waku node and have their web app connect to it.
- U2. Potential WSS/HTTPS issues are worked around so that developer does need to manually generate or import SSL certificates.
- U3. There is an easy option for the developer to bootstrap and connect to local node, instead of external peers.

- S1. Linux and Mac development environments.
- S2. Local network without RLN.
- S3. Chrome and Firefox browsers.
