Exporting the Hasura GraphQL schema

If you need to share, introspect or export the GraphQL schema, you can use community tooling such as
`graphqurl <https://github.com/hasura/graphqurl>`__, `Apollo CLI <https://github.com/apollographql/apollo-tooling>`__,
`get-graphql-schema <https://github.com/prismagraphql/get-graphql-schema>`__, etc.
Using **graphqurl**
-------------------
For example, using ``graphqurl``, you can get the schema as follows:
Run ``npm install -g graphqurl`` to install ``graphqurl``. Then you can run the following commands to download the
GraphQL schema:
.. code-block:: bash
# If the GraphQL engine is running at https://my-graphql-engine.com/v1/graphql,
# without an admin secret
gq https://my-graphql-engine.com/v1/graphql --introspect > schema.graphql
# If Hasura GraphQL engine is running with an admin secret
gq https://my-graphql-engine.com/v1/graphql -H 'X-Hasura-Admin-Secret: adminsecretkey' --introspect > schema.graphql
By default, it downloads the schema in ``.graphql`` format. If you want it in JSON format, you can use an additional
flag ``--format json``:
.. code-block:: bash
# Getting the schema in .json format
gq https://my-graphql-engine.com/v1/graphql --introspect --format json > schema.json
Using **Apollo CLI**
--------------------
Using Apollo CLI, you can get the schema as follows:
Run ``npm install -g apollo`` to install the Apollo CLI. You can then run the following command to download the GraphQL schema:
.. code-block:: bash
# If the GraphQL engine is running at https://my-graphql-engine.com/v1/graphql,
# without an admin secret
apollo schema:download --endpoint https://my-graphql-engine.com/v1/graphql
# If Hasura GraphQL engine is running with an admin secret
apollo schema:download --endpoint https://my-graphql-engine.com/v1/graphql --header 'X-Hasura-Admin-Secret: adminsecretkey'
Note that ``apollo schema:download`` is an alias of the command `apollo service:download <https://github.com/apollographql/apollo-tooling#apollo-servicedownload-output>`__.
By default, this downloads the schema to a file called ``schema.json``. This command has no other output types.
