50-53: Use parameterized queries to prevent SQL injectionIn the query fetching community policies, variables are interpolated directly into the SQL string:
const [policy]: {...} = await queryRunner.query( `SELECT id, community_policy.member, community_policy.lead, community_policy.admin FROM community_policy WHERE id = '${community.policyId}'` );This practice can lead to SQL injection vulnerabilities. Even though this is a migration script and the data is controlled, it's a best practice to use parameterized queries to enhance security.
You can modify the query to use parameters:
- const [policy]: {...} = await queryRunner.query( - `SELECT id, community_policy.member, community_policy.lead, community_policy.admin FROM community_policy WHERE id = '${community.policyId}'` - ); + const [policy]: {...} = await queryRunner.query( + `SELECT id, community_policy.member, community_policy.lead, community_policy.admin FROM community_policy WHERE id = ?`, + [community.policyId] + );

76-79: Avoid string interpolation in database queriesWhen querying for the parent community, the
community.parentCommunityIdis directly injected into the SQL string:const [parentCommunity]: {...} = await queryRunner.query( `SELECT id, roleSetId FROM community WHERE id = '${community.parentCommunityId}'` );To prevent potential security risks and adhere to best practices, use parameterized queries.
Update the query as follows:
- const [parentCommunity]: {...} = await queryRunner.query( - `SELECT id, roleSetId FROM community WHERE id = '${community.parentCommunityId}'` - ); + const [parentCommunity]: {...} = await queryRunner.query( + `SELECT id, roleSetId FROM community WHERE id = ?`, + [community.parentCommunityId] + );

71-73: Gracefully handle missing policiesCurrently, the code throws an error if a policy is not found:
if (!policy) { throw Error(`No policy found for community: ${community.id}`); }Consider handling this scenario more gracefully, perhaps by logging a warning and continuing with the migration, or by validating that all communities have policies before running the migration. This will prevent the migration from failing unexpectedly.

95-107: Enhance readability by documenting boolean parametersIn the calls to
this.createRole, boolean arguments are passed without context:await this.createRole( queryRunner, 'member', policy.member, roleSetID, 0, 9, false, memberRequiresParentRole );Boolean parameters can be unclear. To improve readability, consider using named constants or comments to indicate the purpose of each boolean value.
For example:
await this.createRole( queryRunner, 'member', policy.member, roleSetID, 0, 9, /* requiresEntryRole */ false, /* requiresSameRoleInParentRoleSet */ memberRequiresParentRole );
118-118: Correct indentation for consistent code formattingThere's an indentation inconsistency on line 118, which affects readability:
policy.admin,Adjust the indentation to align with the surrounding code:
- policy.admin, + policy.admin,(Note: Ensure that the line is indented consistently with the other parameters.)

200-240: Wrap migration steps in a transaction for atomicityThe migration performs multiple database operations that should either all succeed or all fail together. Wrapping these operations in a transaction ensures that the database remains consistent in case of an error.
Modify the
upmethod to use a transaction:public async up(queryRunner: QueryRunner): Promise<void> { await queryRunner.startTransaction(); try { // Existing migration code // ... await queryRunner.commitTransaction(); } catch (err) { await queryRunner.rollbackTransaction(); throw err; } }
Line range hint
280-289: Use strict typing for JSON parsingIn the
createRolefunction, JSON strings are parsed without specifying the expected type:const communityRolePolicy: CommunityPolicy = JSON.parse(communityPolicyStr);Consider using a type guard or validation to ensure that the parsed object conforms to the
CommunityPolicytype, enhancing type safety and preventing runtime errors.

291-305: Validate input data before insertionWhen constructing the
userPolicy,organizationPolicy, andvcPolicyobjects, ensure that the values are validated. For example, check thatminimumandmaximumnumbers are within acceptable ranges and thatminimumis not greater thanmaximum.To automate verification, you can run the following script to check for any policies where
minUseris greater thanmaxUser:Replace
sqlite3 your_database.dbwith the appropriate command to access your database.
