-------------------------------------------------------------------------------- /.github/CONTRIBUTING.md: -------------------------------------------------------------------------------- 1 | # Contributing guide 2 | 3 | 1. Create a new directory in the `gateways` folder with the name of the new gateway. 4 | 2. Prepare the `install.sh` script that will install the necessary dependencies, the gateway itself. 5 | 3. Create the `run.sh` script that will start the gateway. See an example using [supergraph.graphql](../gateways/grafbase-gateway/run.sh) and [subgraphs information](../gateways/cosmo-router/run.sh). 6 | 4. Add the `gateway.json` file with the necessary information about the gateway. See an example [here](../gateways/hive-gateway/gateway.json). 7 | 5. The `.gitignore` should be created as well to avoid committing unnecessary files. 8 | 6. Execute `make test-[name of the gateway]` to test your gateway. 9 | 7. Run `make summary` to include your gateway in the results. 10 | -------------------------------------------------------------------------------- /.gitignore: -------------------------------------------------------------------------------- 1 | node_modules 2 | dist 3 | .DS_Store 4 | gateways/*/logs/*.log -------------------------------------------------------------------------------- /.node-version: -------------------------------------------------------------------------------- 1 | 22.16 -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | MIT License 2 | 3 | Copyright (c) 2024 - The Guild 4 | 5 | Permission is hereby granted, free of charge, to any person obtaining a copy 6 | of this software and associated documentation files (the "Software"), to deal 7 | in the Software without restriction, including without limitation the rights 8 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 9 | copies of the Software, and to permit persons to whom the Software is 10 | furnished to do so, subject to the following conditions: 11 | 12 | The above copyright notice and this permission notice shall be included in all 13 | copies or substantial portions of the Software. 14 | 15 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 16 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 17 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
