# ChirpStack gRPC to REST API proxy
2+
3+
The ChirpStack gRPC to REST API proxy exposes the ChirpStack (v4) gRPC as REST
4+
API. While the gRPC API interface exposed by ChirpStack (v4) is recommended,
5+
in some use-cases a REST API cna be more convenient. It could also help when
6+
migrating from ChirpStack v3 to v4 as previously this proxy was embedded inside
7+
the ChirpStack Application Server.
8+
9+
## Usage
10+
11+
```bash
12+
chirpstack-rest-api --server localhost:8080 --bind 0.0.0.0:8090 --insecure
13+
```
14+
15+
* `--server` points to the ChirpStack gRPC endpoint. If ChirpStack is installed
16+
on the same machine and uses port `8080` (default), you can use the default
17+
value. You can also use the environment variable `SERVER`.
18+
* `--bind` defines to which interface and port the REST API server will bind.
19+
In the above example (and default value), the REST API server will be exposed
20+
on port `8090`. YOu can also use the environment variable `BIND`.
21+
* `--insecure` indicates that the gRPC interface is not secured using a TLS
22+
certificate. You can also use the environment variable `INSECURE` (setting
23+
this to any value enables insecure mode, e.g. do not use `INSECURE=false`!).
24+
25+
## Building from source
26+
27+
To start the Docker Compose based development environment:
28+
29+
```
30+
make devshell
31+
```
32+
33+
Within this development shell, you can use one of the following commands
34+
(see also the included `Makefile`):
35+
36+
```bash
37+
# Compile binary
38+
make build
39+
40+
# Create distributable archives and packages.
41+
make dist
42+
43+
# Create snapshot archives and packages.
44+
make snapshot
45+
46+
# Re-generate API definitions (VERSION must be set to the ChirpStack version)
47+
VERSION=v4.0.0 make generate
48+
```
