Relay

The Hasura GraphQL Engine serves Relay schema for Postgres tables which has a primary key defined.

The Relay schema can be accessed through /v1/relay endpoint.

[Add docs links][add console screenshot for relay toggle]

Remote Joins

Remote Joins extend the concept of joining data across tables, to being able to join data across tables and remote schemas.

It works similar to table relationships. Head to the Relationship tab in your table page and define a remote relationship:

  1. give a name for the relationship
  2. select the remote schema
  3. give the join configuration from table columns to remote schema fields.

[Add docs links][add console screenshot]

Scheduled Triggers

A scheduled trigger can be used to execute custom business logic based on time. There are two types of timing events: cron based or timestamp based.

A cron trigger will be useful when something needs to be done periodically. For example, you can create a cron trigger to generate an end-of-day sales report every weekday at 9pm.

You can also schedule one-off events based on a timestamp. For example, a new scheduled event can be created for 2 weeks from when a user signs up to send them an email about their experience.

(close #1914)

Allow access to session variables by computed fields (fix #3846)

Sometimes it is useful for computed fields to have access to the Hasura session variables directly. For example, suppose you want to fetch some articles but also get related user info, say likedByMe. Now, you can define a function like:

CREATE OR REPLACE FUNCTION article_liked(article_row article, hasura_session json)
RETURNS boolean AS $$
  SELECT EXISTS (
    SELECT 1
    FROM liked_article A
    WHERE A.user_id = hasura_session ->> 'x-hasura-user-id' AND A.article_id = article_row.id
  );
$$ LANGUAGE sql STABLE;

and make a query like:

query {
  articles {
    title
    content
    likedByMe
  }
}

Support for this is now added through the add_computed_field API.

Read more about the session argument for computed fields in the docs.

Manage seed migrations as SQL files

A new seeds command is introduced in CLI, this will allow managing seed migrations as SQL files

Creating seed

# create a new seed file and use editor to add SQL content
hasura seed create new_table_seed

# create a new seed by exporting data from tables already present in the database
hasura seed create table1_seed --from-table table1

# create from data in multiple tables:
hasura seed create tables_seed --from-table table1 --from-table table2

Applying seed

# apply all seeds on the database:
hasura seed apply

# apply only a particular seed
hasura seed apply --file 1234_add_some_seed_data.sql

v1.2.0

Include the changelog from v1.2.0-beta.1, v1.2.0-beta.2, v1.2.0-beta.3, v1.2.0-beta.4, v1.2.0-beta.5

Additional changelog:

CLI: Support servers with self-signed certificates (close #4564) (#4582)

A new flag --certificate-authority is added so that the CA certificate can be provided to trust the Hasura Endpoint with a self-signed SSL certificate.

Another flag --insecure-skip-tls-verification is added to skip verifying the certificate in case you don't have access to the CA certificate. As the name suggests, using this flag is insecure since verification is not carried out.

  • docs: update actions docs (#4586)

v1.2.0-beta.5

server: backend only insert permissions

Introduces optional backend_only (default: false) configuration in insert permissions (see api reference). If this is set to true, the insert mutation is accessible to the role only if the request is accompanied by x-hasura-use-backend-only-permissions session variable whose value is set to true along with the x-hasura-admin-secret header. Otherwise, the behavior of the permission remains unchanged.

This feature is highly useful in disabling insert_table mutation for a role from frontend clients while still being able to access it from a Action webhook handler (with the same role).

(rfc #4120) (#4224)

server: debugging mode for non-admin roles

For any errors the server sends extra information in extensions field under internal key. Till now this was only available for admin role requests. To enable this for other roles, start the server with --dev-mode flag or set HASURA_GRAPHQL_DEV_MODE env variable to true:

$ graphql-engine --database-url <database-url> serve --dev-mode

In case you want to disable internal field for admin role requests, set --admin-internal-errors option to false or or set HASURA_GRAPHQL_ADMIN_INTERNAL_ERRORS env variable to false

$ graphql-engine --database-url <database-url> serve --admin-internal-errors false

This feature come in handy during development when you may want to see detailed errors irrespective of roles.

Improved internal errors for Actions:

(This is a breaking change with previous 1.2.0-beta releases)

The internal field for action errors is improved with more debug information. It now includes request, response and error fields instead of just webhook_response field.

Before:

{
  "errors": [
    {
      "extensions": {
        "internal": {
          "webhook_response": {
            "age": 25,
            "name": "Alice",
            "id": "some-id"
          }
        },
        "path": "$",
        "code": "unexpected"
      },
      "message": "unexpected fields in webhook response: age"
    }
  ]
}

After:

{
  "errors": [
    {
      "extensions": {
        "internal": {
          "error": "unexpected response",
          "response": {
            "status": 200,
            "body": {
              "age": 25,
              "name": "Alice",
              "id": "some-id"
            },
            "headers": [
              {
                "value": "application/json",
                "name": "Content-Type"
              },
              {
                "value": "abcd",
                "name": "Set-Cookie"
              }
            ]
          },
          "request": {
            "body": {
              "session_variables": {
                "x-hasura-role": "admin"
              },
              "input": {
                "arg": {
                  "age": 25,
                  "name": "Alice",
                  "id": "some-id"
                }
              },
              "action": {
                "name": "mirror"
              }
            },
            "url": "http://127.0.0.1:5593/mirror-action",
            "headers": []
          }
        },
        "path": "$",
        "code": "unexpected"
      },
      "message": "unexpected fields in webhook response: age"
    }
  ]
}

cli: add support for .env file

ENV vars can now be read from .env file present at the project root directory. A global flag, --envfile, is added so you can explicitly provide the .env filename, which defaults to .env filename if no flag is provided.

Example:

hasura console --envfile production.env

The above command will read ENV vars from production.env file present at the project root directory.

(close #4129) (#4454)

console: allow setting post-update check in update permissions

Along with the check for filtering rows that can be updated, you can now set a post-update permission check that needs to be satisfied by the updated rows after the update is made.

(close #4142) (#4313)

console: support for Postgres materialized views

Postgres materialized views are views that are persisted in a table-like form. They are now supported in the Hasura Console, in the same way as views. They will appear on the 'Schema' page, under the 'Data' tab, in the 'Untracked tables or views' section.

(close #91) (#4270)

docs: map Postgres operators to corresponding Hasura operators

Map Postgres operators to corresponding Hasura operators at various places in docs and link to PG documentation for reference. For example, see here.

v1.2.0-beta.3

console: manage Postgres check constraints

Postgres Check constraints allows you to specify that the value in a certain column must satisfy a Boolean (truth-value) expression. They can be used to put in simple input validations for mutations and with this release, these constraints can now be added while creating a table or later from Modify tab on the console.

Example: When a product is created, ensure that the price is greater than zero. The SQL would look like this:

CREATE TABLE products (
    product_id UUID DEFAULT gen_random_uuid(),
    name TEXT,
    price NUMERIC CONSTRAINT positive_price CHECK (price > 0)
);

To create this table with Hasura Console, on the 'Add a new table' screen, after adding all the columns, scroll down to 'Check constraints' section and 'Add a new check constraint' with the following properties:

  • Constraint name: positive_price
  • Check expression: price > 0

Read more about check constraints on Postgres Docs.

(close #1700) (#3881)

CLI: V2 migrations architecture

A new CLI migrations image is introduced to account for the new migrations workflow. If you're have a project with version: 2 in config.yaml, you should use the new image: hasura/graphql-engine:v1.2.0-cli-migrations-v2. Mount the migrations at /hasura-migrations and metadata at /hasura-metadata.

v1.2.0-beta.1

Hasura Actions

Actions are a way to extend Hasura’s auto-generated mutations with entirely custom ones which can handle various use cases such as data validation, data enrichment from external sources and any other complex business logic.

A new mutation can be created either by defining its GraphQL SDL or by deriving it from an existing Hasura-generated mutation. The resolver is exposed to Hasura as a webhook which can be called synchronously or asynchronously. This release also includes an ever evolving codegen workflow to make managing the custom resolvers easier.

Read more about actions in the docs.

(#3042) (#3252) (#3859)

Downgrade command

A new command is added to the server executable for downgrading to earlier releases. Previously, if you ran a newer Hasura version and wanted to go back to an old version on the same database, you had to stop Hasura, run some SQL statements and start Hasura again. With the new downgrade command, these SQL statements can be run automatically.

Example: Downgrade from v1.2.0 to v1.0.0:

# stop hasura v1.2.0

# run the following command:
docker run hasura/graphql-engine:v1.2.0 graphql-engine --database-url <db-url> downgrade --to-v1.0.0

# start hasura v1.0.0

Read more about this command in the docs.

(close #1156) (#3760)

Expiration of connections authenticated by WebHooks

When using webhooks to authenticate incoming requests to the GraphQL engine server, it is now possible to specify an expiration time; the connection to the server will be automatically closed if it's still running when the expiration delay is expired.

Read more about it in the docs.
