# 30-haskell-traverse-resolution
|
||
|
|
|
||
|
|
This example shows intermediate Haskell batch resolution with `traverse`.
|
||
|
|
|
||
|
|
It includes:
|
||
|
|
|
||
|
|
- a deployment request type parsed from compact CLI input,
|
||
|
|
- a service catalog with per-service release metadata,
|
||
|
|
- one `traverse` pass that resolves every request or fails the whole batch, and
|
||
|
|
- a test suite run by `nix flake check`.
|
||
|
|
|
||
|
|
Useful commands:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
nix develop
|
||
|
|
cabal run
|
||
|
|
cabal run -- api:production:stable worker:staging:candidate auth:production:stable
|
||
|
|
cabal test
|
||
|
|
|
||
|
|
nix build
|
||
|
|
./result/bin/mini-resolution api:production:stable worker:staging:candidate auth:production:stable
|
||
|
|
|
||
|
|
nix run . -- api:production:stable worker:staging:candidate auth:production:stable
|
||
|
|
nix flake check
|
||
|
|
```
